My new task: Improve performance of an archiving algorithm.
"We don't know what the cause of the performance issues is." I can tell you: Because it's overengineered bullshit! This is spaghetti inside spaghetti on top of spaghetti!
And it doesn't help that they don't want to know about different archiving algorithms, because I offered multiple alternatives, one 80% smaller than the other, but the other is 80% faster.
At least I'm instructed to throw it all away and rewrite it and not add even more to the garbage pile. I'm very happy about that.
