Search - "why is our application slow?"
-
After listening to two of our senior devs play ping pong with a new member of our team for TWO DAYS!
DevA: "Try this.."
Junior: "Didn't work"
DevB: "Try that .."
Junior: "Still not working"
I ask..
Me:"What is the problem?"
Few ums...uhs..awkward seconds of silence
Junior: "App is really slow. Takes several seconds to launch and searching either crashes or takes a really long time."
DevA: "We've isolated the issue with Entity Framework. That application was written back when we used VS2010. Since that application isn't used very often, no one has had to update it since."
DevB: "Weird part is the app takes up over 3 gigs of ram. Its obviously a caching issue. We might have to open up a ticket with Microsoft."
Me: "Or remove EF and use ADO."
DevB: "That would be way too much work. The app is supposed to be fully deprecated and replaced this year."
Me: "Three of you for the past two days seems like a lot of work. If EF is the problem, you remove EF."
DevA: "The solution is way too complicated for that. There are 5 projects and 3 of those have circular dependencies. Its a mess."
DevB: "No fracking kidding...if it were written correctly the first time. There aren't even any fracking tests."
Me:"Pretty sure there are only two tables involved, maybe 3 stored procedures. A simple CRUD app like this should be fairly straight forward."
DevB: "Can't re-write the application, company won't allow it. A redesign of this magnitute could take months. If we can't fix the LINQ query, we'll going to have the DBAs change the structures to make the application faster. I don't see any other way."
Holy frack...he didn't just say that.
Over my lunch hour, I strip down the WPF application to the basics (too much to write about, but the included projects only had one or two files), and created an integration test for refactoring the data access to use ADO. After all the tests and EF removed, the app starts up instantly and searches are also instant. Didn't click through all the UI, but the basics worked.
Sat with Junior, pointed out my changes (the 'why' behind the 'what') ...and he how he could write unit tests around the ViewModel behavior in the UI (and making any changes to the data access as needed).
Today's standup:
Junior: "Employee app is fixed. Had some help removing Entity Framework and how it starts up fast and and searches are instant. Going to write unit tests today to verify the UI behaivor. I'll be able to deploy the application tomorrow."
DevA: "What?! No way! You did all that yesterday?"
Me: "I removed the Entity Framework over my lunch hour. Like I said, its basic CRUD and mostly in stored procedures. All the data points are covered by integration tests, but didn't have time for the unit tests. It's likely I broke some UI behavior, but the unit tests should catch those."
DevB: "I was going to do that today. I knew taking out Entity Framework wouldn't be a big deal."
Holy fracking frack. You fracking lying SOB. Deeeep breath...ahhh...thanks devRant. Flame thrower event diverted.13 -
1. Do you know why my computer is so slow?
2. What cellphone do you recommend me to buy? (They always end up buying the cheapest)
3. What do you do at work? (Answer: "I create applications". Anything more complex than that is not going to be understood or they will loose interest)
4. Something is wrong with the: [TV, Cellphone, microwave, etc.]. Could you please take a look? (Believe or not, if something works with electricoty, my family thinks I can fix it).
5. Is it true that if I send this WhatsApp message to all my contacts I will have more options?
6. I need to build an application that (pretty much The Matrix), how much time do you need and how much would cost? Don't you dare to give me wrong numbers. (We have to see the future)
7. (Continuing the previous point, a non-technical client) I don't think that would take so much time/money. (Every time)
8. I want to use the latest Front-End frameworks. I want to see all those beautiful animations in my page and that it runs smoothly... I also need that it runs in IE 5.
9. So, you have been working in the back end? If you don't have a screen to show to the client is like you didn't do anything in this sprint.
10. Why haven't you built and million dollar application? Everybody is doing that right now....
Yep, those are only a few downsides of our profession if we count family, friends and even co-workers. But I can't imagine myself doing anything else.6 -
How NOT to make applications:
- single GET request called rather frequently
- 3304 SELECTs per request
- Some of them lasting ~50ms9 -
I think I want to quit my first applicantion developer job 6 months in because of just how bad the code and deployment and.. Just everything, is.
I'm a C#/.net developer. Currently I'm working on some asp.net and sql stuff for this company.
We have no code standards. Our project manager is somewhere between useless and determinental. Our clients are unreasonable (its the government, so im a bit stifled on what I can say.) and expect absurd things from us. We have 0 automated tests and before I arrived all our infrastructure wasn't correct to our documentation... And we barely had any documentation to begin with.
The code is another horror story. It's out sourced C# asp.net, js and SQL code.. And to very bad programmers in India, no offense to the good ones, I know you exist. Its all spagheti. And half of it isn't spelled correctly.
We have a single, massive constant class that probably has over 2000 constants, I don't care to count. Our SQL projects are a mess with tons of quick fix scripts to run pre and post publishing. Our folder structure makes no sense (We have root/js and root/js1 to make you cringe.) our javascript is majoritly on the asp.net pages themselves inline, so we don't even have minification most of the time.
It's... God awful. The result of a billion and one quick fixes that nobody documented. The configuration alone has to have the same value put multiple times. And now our senior developer is getting the outsourced department to work on moving every SINGLE NORMAL STRING INTO THE DATABASE. That's right. Rather then putting them into some local resource file or anything sane, our website will now be drawing every single standard string from the database. Our SENIOR DEVELOPER thinks this is a good idea. I don't need to go into detail about how slow this is. Want to do it on boot? Fine. But they do it every time the page loads. It's absurd.
Our sql database design is an absolute atrocity. You have to join several tables together just to get anything done. Half of our SP's are failing all the time because nobody really understands the design. Its gloriously awful its like.. The epitome of failed database designs.
But rather then taking a step back and dealing with all the issues, we keep adding new features and other ones get left in the dust. Hell, we don't even have complete browser support yet. There were things on the website that were still running SILVERLIGHT. In 2019. I don't even know how to feel about it.
I brought up our insane technical debt to our PM who told me that we don't have time to worry about things like technical debt. They also wouldn't spend the time to teach me anything, saying they would rather outsource everything then take the time to teach me. So i did. I learned a huge chunk of it myself.
But calling this a developer job was a sick, twisted joke. All our lives revolve around bugnet. Our work is our BN's. So every issue the client emails about becomes BN's. I haven't developed anything. All I've done is clean up others mess.
Except for the one time they did have me develop something. And I did it right and took my time. And then they told me it took too long, forced me to release before it was ready, even though I had never worked on what I was doing before. And it worked. I did it.
They then told me it likely wouldn't even be used anyway. I wasn't very happy at all.
I then discovered quickly the horrors of wanting to make changes on production. In order to make changes to it, we have to... Get this
Write a huge document explaining why. Not to our management. To the customer. The customer wants us to 'request' to fix our application.
I feel like I am literally against a wall. A huge massive wall. I can't get constent from my PM to fix the shitty code they have as a result of outsourcing. I can't make changes without the customer asking why I would work on something that doesn't add something new for them. And I can't ask for any sort of help, and half of the people I have to ask help from don't even speak english very well so it makes it double hard to understand anything.
But what can I do? If I leave my job it leaves a lasting stain on my record that I am unsure if I can shake off.
... Well, thats my tl;dr rant. Im a junior, so maybe idk what the hell im talking about.rant code application bad project management annoying as hell bad code c++ bad client bad design application development16 -
I'm having an existential crisis with this client.
We are spending millions of $s every year to make sure the product's performance is perfect. We are testing various scenarios, fine-tuning PLABs: the environment, application, middleware, infra,... And then we provide our recommendations to the client: "To handle load of XX parallel users focusing on YY, yy and Zy APIs, use <THIS> configuration".
And what the client does?
- take our recommendations and measure the wind speed outside
- if speed is <20m/s and milk hasn't gone bad yet, add 2x more instances of API X
- otherwise add 3xX, 1xY and give more CPUs to Z
- split the setup in half and deploy in 2 completely separate load-balanced prod environments.
- <do other "tweaking">
- bomb our team with questions "why do we have slow RTs?", "why did the env crash?", "why do we have all those errors?", "why has this been overlooked in PLABs?!?"
If you're improvising despite our recommendations, wtf are we doing here???
One day I will crack. Hopefully, not sometime soon.3 -
A CASE AGAINST BLUE PRISM
Let's review one of the worst weeks I had with Blue Prism
Monday: Yay! Solved one of the problems we've been carrying around for a week before.
One of the robots suddenly became slow. Like, REAL slow. A process that would take 3 minutes per record now takes 45, and that broke apart all the following schedule.
There were no updates on the application server, the production machine, the robot, it just became slow. And not always slow; a process manually run from console room would work, a process in debug room would work, it's just the scheduled part that caused problems.
It turned out, BP didn't seem to like that particular combination of schedulation + process + machine. Moving the process to a different machine seemingly fixed that. IDK why.
Tuesday: One of our processes waits for a code to appear in the page, and when that happens, it memorizes this code. However, now it is always returning blank. Worked for months, now it breaks every single time.
After half a day of debugging a bug which DIDN'T HAPPEN IN DEBUG MODE YET AGAIN, at 11pm I decided to just place a nonsensical timeout in page before reading and call it a day.
WEDNESDAY: a scheduled process didn't start. "No sessions created". Thanks Blue Prism, very cool.
THURSTAY: This time, schedulation did start, but the process is "waiting". As in: it's 9:30 am, the process has been stuck in the same step since 6:00 am. Turns out, it blocked during a navigate stage; you need to send a string to clipboard using the standard BP action for that, then paste and click "enter", but for some reason the standard BP object sent "ORRCO" instead of "ORRICO" to clipboard, which obviously returned no results and then... the process just didn't feel like doing things anymore. No errors, no logs, nothing: just sitting on its ass. Because fuck you that's why.
Friday: another process uses a very moderate amount of scripts to work. Nothing really fancy, just a couple of lines of code to place in page some IDs and selector to help BP do its thing, otherwise selecting these elements would be a nightmare.
But
Failed while invoking javascript method:Exception from HRESULT: 0x80020101-> at mshtml.HTMLWindow2Class.IHTMLWindow2_execScript(String code, String language)
The same script -it's not dynamically generated-worked yesterday, the day before and the day after. But sometimes it will not. Why? The answer, my friend, is blowin'' in the wind
