Description David Woodhouse 2012-05-19 23:39:43 UTC 
I archive mail quarterly, and when it happens I see thousands of messages disappear from each mailbox. This always used to work reasonably, but in 3.4 it seems to take about 40ms for each call to camel_folder_summary_remove_uid().

This means that it takes *minutes* to sync each folder, just for the local database work of removing old messages from the cache. This is an entirely unacceptable performance regression.

Proposed fix

This patch reduces the time per message from about 40ms to about 50µs.
