cd /usr/bin
ls -l
works fine.

'ls -l' in any big dir (with more than 100 files) in /var1 or /var2 doesn't work or works very slowly. btw, 'ls' without options works fine. Problem is appeared on this hardware after upgrade 4.11-STABLE to 6.2-STABLE.

 Removing all but a few users from the master password file will eliminate
 the extreme slowdown in ls -l response time which would suggest it is
 related to uid to name resolution.
 
 This is an extremely annoying issue and it is beyond belief that few if
 any people haven't escalated this bug to a high level.
 
 I have access to two FreeBSD 6.2 stable machines that have this problem.
 
 If anyone has a solution, fix or workaround, please share.
