I checked with the developer, and no-one running 6.x and quotas ever replied to multiple requests to test the patch. It can be found here if you want to resolve this performance problem without upgrading to 7.0:

Well, I'm running RELENG_6 SMP system with this patch since september
2007 (last updated 2008-02-08), and I haven't seen any quota-related
problem. Quota-enabled partition is 60 GB UFS2 containing 25,000+
customers' home directories with Maildir-style mailboxes and surviving
100,000+ deliveries (file creations) and approximately the same number
of retrievals (file deletions) each day.

mail:~# df -i /disk1

mail:~# mount
/dev/da1s1d on /disk1 (ufs, local, noexec, nosuid, with quotas, soft-updates)

If I can run some specific (stress?) tests that might provide useful
information, let me know. Output of dmesg, vmstat, iostat, top, etc --
just ask.

Thanks, that is precisely the kind of feedback we are looking for.
