My company piles so much ill-considered Linux antivirus and other crap in cloud developer boxes that even on a huge instance type, the builds are ten or more times slower than a laptop, and hundreds of times slower than a real dev box with a Threadripper or similar. It's just a pure waste of money and everyone's time.

It turns out that hooking every system call with vendor crapware is bad for a unix-style toolchain that execs a million subprocesses.
