519495 - Excessive disk load

Status: RESOLVED DUPLICATE of bug 491283

(Thunderbird :: General, defect)

Description

[bingotheclowno]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
Build Identifier: 2.0.0.23

I have two email addresses set up.One goes to local folders, one to its own folder.After a fresh Thunderbird start, when I click on the Inbox of the secondary email address, Thunderbird freezes for a long while (30-40s) while reading the disk.Using ntfilemon (sysinternals.com) I determined it loads all the fonts available in %systemroot%\Fonts, which in my case are around 8k files.
My system isn't the fastest system around, but not the opposite either.
Don't know if this is normal and expected behavior.

Reproducible: Always

Steps to Reproduce:
1.Start thunderbird (automatically connects to get new mail)
2.Click on the Inbox of the alternate email address (the one that isn't stored under local folders)
3.Thunderbird is unresponsive and causes a lot of disk usage while loading all the fonts.

See bug 491283, although that speaks about a startup problem. Apparently, T-bird reads the font a little later, when the first inbox is opened. Anyway, bug 491283 is supposed to give some kind of performance boost (with a font cache or something similar).

See also bug 517045, even though that only speaks about the Mac, but it will affect font initialisation. And it's ready to be checked in.

oops, forget bug 517045, it really is Mac only.
