Mere 25-30 years ago I saw some very chatty Java builds run faster if the terminal window was obscured or minimized. Slow console output held back the compilers.

In about 2013 I was an intern at Microsoft and my mentor showed me that if you were running something that streamed a lot to the terminal, it would run faster if you covered it with another window (but didn't minimize it, for some reason I don't recall). I was surprised this kind of trick was still a thing.
I have reduced build times of Java projects on our Jenkins CI by half (like from 15min to 7min) just by disabling extra logging the application did during tests. Logs can be real slow.
"A lot" is quite a bit of an overstatement. I don't remember the exact numbers, but my program, which updated stats (about 100 chars + '\r') every 0.1s, was becoming noticeably faster if these stats were disabled. so, the update speed was at most 100 KB/s
