Hey folks,
After vetting 1.4.20 on a development server, I rolled it out to
my colocated server successfully.
Since then, the performance in the web interface has taken a
pretty bad hit. With 1.4.19, bringing up each email was almost
instantaneous, now there is a several second lag between each one.
Looking at the server, I see Apache hitting the CPU harder
than it normally does, taking about 10% of the CPU with the child
I'm connecting to.
The only change I've made recently is to install the
server_settings and server_settings_backend plugins, but I disabled
them and the problem remains. Switching back to 1.4.19 makes the
performance recover to what I saw before the upgrade.
I have the following plugins installed and enabled:
delete_move_next
compatability
calendar_sql_backend
calendar (shared_calendars)
listcommands
newmail
bounce
add_address
squirrel_logger
view_as_html
message_details
sent_subfolders
quicksave
show_headers
server_settings_backend
server_settings
This server is not shared hosting or anything, it's my own
physical box running very little other than SpamAssassin and
ClamAV in the background. It's on OpenBSD -CURRENT, with OpenBSD's
version of Apache 1.3.29 and PHP 5.2.12. I run dovecot 1.1.20 in
the backend.
I'm not complaining, the performance is still acceptable, it's
just a mild annoyance. Has anyone else seen any performance hits
with 1.4.20?
Thanks!
Benny
