[imp] Seeking advice on slow login times (follow-up)

[Walter R. Moore]

I left out a couple details -

IMAP server version is UW-IMAP imap-2004g
Postgres server version is postgres 8.1.4
Apache and PHP are rebuilt Red Hat rpms (httpd 2.0.55 and php 4.3.9)

The various test.php pages give me a clean bill of health.
