TCP is giant.
Matt Might was a resident, I paired with Chase, I played with hashtables, and started working on Ludum Dare this week.
The final optimization for the pstree clone was to replace file globbing with readdir and a custom isInt function.
I changed from using ioutil’s ReadAll, over to bufio’s ReadFrom, into os.File’s Read for more gross performance gains.
I made my pstree clone faster by swapping the regex with string functions. I dived in kernel code for more ridiculous things.
