Hi,
I have many mail and I decided to install the squirrelmail folder size plugin from here:
http://squirrelmail.org/plugin_view.php?id=87

I installed it, enabled it, I can click on folder dimension,
when I click it it redirect me
https://www.myserver.org/webmail/plugin ... _sizes.php

my CPU goes up to 90% for many seconds, than nothing is outputted.

Have you got an idea on why of this problem?

I tried with a different email account with less emails and it works.

Its very unuseful if the plugn isn't able to work with many emails.

I solved by enlarging the PHP timeout with
set_time_limit(60);
in the plugin file.

I think that this plugin should enlarge the timeout period by default.
