30752 - Scrolling through messages using keyboard is slow

Status: VERIFIED FIXED

(SeaMonkey :: MailNews: Message Display, defect, P3)

Description

[Richard Zach]

Scrolling through messages using the keyboard up and down keys is exceedingly
slow.  Apparently every single message is opened and displayed, making fast
scrolling impossible.  There should be some way to check whether another key
event happened before downloading/opening/displaying a message and moving to
another message accordingly.

Phil found a way to weasel out of owning this bug.  Reassigning.

Scott, reassigning to you because it says perf.  I wasn't sure if someone else
is looking at navigation, so please reassign if I messed up.  Marking M17 since
I think we'd ship beta2 without this fix, please adjust if you disagree.

nominating for beta3 and moving to M18. cc'ing hyatt.  David, is this something 
the tree widget could handle to prevent selection from happening if someone is 
scrolling through a tree using the keyboard?

Hey David, this got fixed with your scrolling performance improvements, right?

reassigning to hyatt.  We think this has improved as part of the scrolling bugs
that hyatt did.  If I'm wrong and this is something that mailnews needs to
control, please reassign back.

This is now speedy. Resolved as fixed.

This is much faster now because we do not seem open and display messages while 
scrolling. I tried srolling through 500 messages on a Linux Performance System, 
took about 190 secs. This is expected because we are scrolling through 
one message at a time.
