I have an odd/frustrating performance problem with Seamonkey 2.24
(although I've been seeing this for several previous versions), running
on Windows 7 Professional. Computer is a bit old, running an Intel
Mobile Core 2 Duo processor, and has 8 GB of RAM.
I use Seamonkey for both browser and mail/news, as well as occasional
work with the HTML composer tool.
Symptoms:
There are times when I'm working in Seamonkey, and I get temporary
freezes (typically 10-20 seconds), where Seamonkey refuses any kind of
input from either keyboard or mouse. When this happens, I can use
Alt-Tab to move from window to Window, but if I do a mouse-over, putting
the pointer over a Seamonkey icon in the Windows Taskbar, most of the
windows show a wait cursor. This happens whether I'm working in the
mail client, the browser, or even the composer. Sometimes, when this
happens, I'll get a switch of focus from one open Seamonkey window to
another (e.g., I'm composing an email message, and suddenly the focus
switches to the browser window).
When the problem happens, I'm not seeing any indication of overall
performance issues on the machine, just Seamonkey. A check of the
Windows Task Manager often shows relatively high CPU usage (up to about
50%) by Seamonkey, whether Seamonkey's memory usage is a few hundred MB,
or over a GB. Restarting Seamonkey seems not to have any effect.
I use Seamonkey on a number of machines, both Windows and Linux, but
this is the only place where I'm seeing this issue. This is my primary
working profile. I typically have 5-10 browser tabs open at a time. In
mail, I have 4 POP accounts active (no IMAP), as well as 4 news servers
defined, and a varying number of newsgroup subscriptions.
I know that the normal first thing to do when addressing performance
issues is to disable extensions (and I have about 30 extensions active),
but I'm finding pretty much the same behavior if I run in Safe Mode.
I've also seen and worked through suggestions relating to Flash
(including disabling the Flash plugin), but no improvement there, either.
To me, this one indicates some sort of background process that's active
(possibly related to mail), but I can't identify it.
I would consider my user profile to not be overly big -- even with a lot
of stored mail from POP accounts, the profile is less than 1 GB, and I'm
pretty aggressive about keeping my Inbox and trash folders pared down.
Given timing of the problem (sometimes, two or three times in an hour),
I'm wondering if there might be something related to POP settings. In
my main working account I have quite a few mail filters active, most for
delivering received content to folders, as well as several search
folders active.
Any ideas of what's happening, and how I might identify what's causing this?
