Anyone got any lesser known Linux optimisation tips?

Yes, install Arch Linux.

To be objective: there are dozens of optimization possibilities. It depends on your specs. HDD, SDD, RAM, CPU?

@tracktraps Samsung 850 Evo 256GB, A6-7310 APU, 8GB 1866Mhz CL13.

To name a few:
1. Install Arch Linux :)
2. I/O Scheduler: noop
3. ZRAM: 4 x 2 GB (2 GB for each core)
4. Symlink cache(s) to /tmp

There are many more. I have several scripts that do this automatically. Maybe I should publish a tuning guide and my scripts on Github.

@tracktraps Please do. That said all those are known optimisations and thus were already applied on my system.

@SHA-16384 In my opinion, It's not worth the effort. Nevertheless, a good tip to save some MB.

@ALMSTJSON nice one for Linux users. Try sudo rm - rf

@moars42 hella fast

@SHA-16384 Not very useful I'm afraid.

@moars42 you forgot the "/" ;)

@ALMSTJSON This isn't Windows.
