Status: VERIFIED WONTFIX

(SeaMonkey :: Preferences, defect, P2)

Description

[Cathleen]

Don't know if this is just noise or not... since measurements are taken from
stop watch.  But, it's probably worth time to investigate... since the other
measurement "Navigator -> Mail & Newsgroups" did not change much, and there is a
large delta for "Open Preference Dialog".  Were there any xul changes in pref
dialog recently??

cc'ing jen, who did the measurements while i was on vacation during that period.
also cc'ing blake (what the heck :).

Comment 3

[sairuh (rarely reading bugmail)]

just to clarify --jen did the tests for the past 3 weeks. the big jump occurred
only with the last set of data. i remember she had sent me email about noticing
the diff: "These numbers were a higher than last week...I did an average of 5
[measurements] versus three, but results seemed fairly consistent."

Comment 4

[Viswanath Ramachandran]

could we get a measurement with a trunk build this week and see what the trend 
is?

Comment 5

[sairuh (rarely reading bugmail)]

yep, the data will be there [see URL] --assuming that the network is behaving
and allows downloads *sigh*.

Comment 6

[sairuh (rarely reading bugmail)]

updated the page with this week's data.

interesting [trunk]: dialog opening is better than last week's. perhaps last
week's was a fluke...?

also, i find it odd that panel switching is worse this week... hm, perhaps it
might be in the difference btwn my dexterity and Jen's. *shrug* (although that
might not account for the dialog opening measurements...}

also #2: i added 6.1 RTM baseline measurements at the end of the page.

nav triage team:

This is not going to get resolved in mozilla0.9.4. Pushing out to mozilla1.0.1
and reassigning to pchen

Comment 9

[[not reading bugmail]]

seth spitzer did quite a few checkins recently that have really given mozilla
some perf, killed some mem-leaks too.

mass-reassign bookmarks & open pref perf bugs from pchen to ben

Comment 11

[Blake Ross]

Does this bug need to be open anymore...?

Comment 12

[Cathleen]

it's too late to figure out this slow down. we don't even have a check-in log to
begin with.  Let's just close this bug and move on.

Comment 13

[sairuh (rarely reading bugmail)]

okay...
