Description mwatson 2001-06-02 06:30:00 UTC 
We found a bug in the Darwin pax where the uid/gid cache was not being used correctly. This resulted in a 10x slowdown of archive extraction in some cases. It's especially bad when archives contain unknown uid/gids

Fix: These diffs may need to be modified to sync up with the current version...
How-To-Repeat: Run pax under gdb. break on getpwuid() & getpwnam(). Notice how often you hit the breakpoints.

I've been hacking on pax a bit, I can take a look at this in a month or so.
