Firefox consumes CPU when accessing tags

Accessing bookmark tags in FF 3.6.11 consumes the CPU 100% for 30+ seconds before browser responds. For example I have a saved search of everything with the tag 'tiddly' and when I access the search I have a significant delay (30+seconds) before the small list displays. Modifying a tag on a bookmark takes a similar lengthy time. This behavior is new with 3.6.11. I can revert back to 3.6.10 and things are OK.

I've confirmed that this problem persists with all plugins removed. I am a heavy user of tags and this problem makes FF unusable for me.

Tried 3.6.12 with the same results. Stuck at 3.6.10 until this is resolved. Or I guess I'll go look at Chrome...

ps. I ended up posting this twice because I can't seem to locate it from a search. It doesn't show up in a search for 'cpu' or 'tags'.

This can be a problem with the file places.sqlite that stores the bookmarks and the history.

Do you have a large amount of bookmarks?

sqlite> select count() from moz_bookmarks;
9933

The DB file is 24M.

Performance is fine with 3.6.10 so something has changed with how the tags are being accessed in 3.6.11.

I'm going to try running some cleanup on the db to see if that helps anything.

Deleted places.sqlite. It was rebuilt on restart to be only 1.8M, partially I suspect because the favicon data was gone for all the sites. In any event the behavior persisted in 3.6.12 - access to a saved search based on a tag pegged the FF process at 100% for about 20 seconds.

In 3.6.10 I notice there is a slight delay, sub-second, when I click on the saved search and later clicks respond immediately.

Something has changed in how tags are being access in the DB from 3.6.10 to 3.6.11.

The problem persists with 3.16.13.  :(

I think this might be related to this bug:

https://bugzilla.mozilla.org/show_bug.cgi?id=595530

Looks like a regression in sqlite3 performance.
