# Read https://chromium.googlesource.com/chromium/src/+/HEAD/docs/mac_build_instructions.md#improving-performance-of-git-commands
# ... and do it all.
sysctl -a | egrep 'max(files|vnodes|proc)' 
# should see
#    kern.maxvnodes: 524288
#    kern.maxproc: 16704
#    kern.maxfiles: 524288
#    kern.maxfilesperproc: 524288


# Useful: https://serverfault.com/questions/502053/difference-between-ulimit-launchctl-sysctl
# launchctl limit maxfiles    # launchctl limit maxproc    

ulimit -a # though setting with ulimit is per-shell . # https://wilsonmar.github.io/maximum-limits/

# The plist files broke in ventura 13.5. https://bugs.chromium.org/p/chromium/issues/detail?id=1467777#c17
# the fix is doing running `ulimit -n 200000` like.. often? lol.
