are there any plans to fix the disk thrashing that occurs with the junk mail filter? or a work around perhaps (other than disabling it, obviously!)?
With the amount of junk mail that most of us receive each day it doesn't make any sence to have an email client without it.
Kinda makes portable thunderbird unusable.
Disable Junk Mail Filter (IMPORTANT) - The adaptive Junk Mail filter in Thunderbird should be disabled for each account you set up. The Junk Mail filter thrashes whatever media it runs from (1,000 to 3,000 I/O writes just for marking a message as junk) which, for our purposes, will decrease flash ram life and cause the application to run *VERY* slow.
