Title:
excessive cpu load during IMAP folder syncronization with large amount
of letters
Status in “thunderbird” package in Ubuntu:
Incomplete
Bug description:
During re-syncronization of IMAP folders with large amount of letters
(over 100k), even with small amount of new letters, thunderbird create
100% CPU load for prolonged time, causing quick laptop's battery
discharge and excessive heating.
Activity manager shows something like 'syncronizing 9 letters', but
operation stalls and take very long time with 100% CPU load.
