787121 - Selecting multiple messages in a folder with a lot of messages causes CPU to spike, application to become unresponsive

Status: RESOLVED DUPLICATE of bug 782899

(Thunderbird :: Folder and Message Lists, defect)

Description

[Matt Dorn]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.82 Safari/537.1

Steps to reproduce:

Just noticed this after upgrading to 15.0.  I have ~500 messages in my Inbox (Gmail account).  I selected 50 of them (holding down Shift and clicking) to bulk delete them.


Actual results:

The CPU spikes and the application becomes unresponsive for several seconds.


Expected results:

The application shouldn't care how many messages you select, and should respond without any trouble.

Matt, this may be dup of bug 782899
Could you take a look there.
One way to prove it is to (temporarily) turn off Gloda indexing and see if the problem goes away.

I guess it's not as simple as disabling Gloda to prove the dup.
Message summaries, and some extensions can cuase this too.

Yes, much of the behavior described in bug 782899 (and especially in bug 753502, which has been tagged as a duplicate of 782899) is similar to my experience, though I never saw much of a memory spike -- only a CPU spike, and the application becoming unresponsive for up to 20 seconds or so.

That said, I did a "Repair Folder" on my Inbox, and that seems to temporarily relieve the problem, allow me to quickly select multiple messages, etc., but the effect is short-lived -- once I start re-ordering, etc., in the folder I'm back to the same problem.

Again, this problem is new with my upgrade to 15.0 today -- never had it before then.

I'm going to mark this as a duplicate, we have two bugs one for memory one for cpu. Just forgot the one aboutt cpu. duping to the most visible one, irving is anyhow working on both issues.
