A common way to debug is to isolate the affected systemcalls, by using
tools like ktrace or strace.
Strace can also record a timestamp, you can see how long it takes to
complete a specific systemcall
# strace -r -f <serverproc>
Do a single login and then examine the results.
happy debugging.

Dennis

Here's the situation. We have an web/ftp server with around 74000 users
defined in the local unix password database. On 4.9-stable which it is
running now, there is no noticable load when lookups are done (logins via
ftp, ~user lookups from apache etc.). We want to migrate this system to
6-stable.
However on 6-STABLE (FreeBSD 6.3-PRERELEASE #0: Wed Dec 5 13:35:05 CET
2007) these same lookups cause very high load and things slow down to a
crawl.
Does anybody have an idea what causes this behavior?
Thanx in advance for any insights.
Take a look to your /etc/nsswitch.conf. If you do not use NIS,
try to change lines for 'group' and 'passwd' to look like this:
group: files
passwd: files
The default value is "compat" on both RELENG_6 and RELENG_7. I don't
think switching to "files" will fix his problem (I'll be very surprised
if it does).
