758899 - Cisco ACS GUI is extremely slow making it unusable

Status: RESOLVED DUPLICATE of bug 760608

(Core :: Networking: HTTP, defect)

Description

[Bill Gianopoulos [:WG9s]]

Since the 4/26 nightly builds the Cisco ACS GUI is completely unusable due to it responding extremely slowly.  This dos not occur with other browsers or earlier versions of Firefox.

Regression range is http://hg.mozilla.org/mozilla-central/pushloghtml?fromcahnge=75c7378c8b6&tochange=cc5254f9823f

Can you test in the Firefox safemode ?
This will be difficult to resolve without testcase

Comment 3

[Bill Gianopoulos [:WG9s]]

I am actually on finding a regression bug using hg bisect.

Comment 4

[Bill Gianopoulos [:WG9s]]

OK somehow the regression range I posted earlier just going back to that post is wrong.  Not sure how i screwed up on that.

What I think I isolated this to was:

http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=75c7378c87b6&tochange=83ef3c9a64b5

Trying to isolate past that was unsuccessful I think I need to redo the bisect doing clobber builds, unfortunately. ;-(

Also, I should explain that what i mean by unusable is that unaffected version display pages with inn 3-4 seconds.  Effected builds take 3-4 minutes plus.

Putting this in the plugins component is a guess because the interface is Java heavy, but I ma not entirely convinced this is not a more generic SSL issue.

Comment 6

[Bill Gianopoulos [:WG9s]]

OK.  please ignore comments 1 and 4.  The correct regression range is:

http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=75c7378c87b6&tochange=cc5254f9825f

Re-doing the bisect.  I also updated mozilla-build, so that I have a version of hg bisect that supports --extend to make the bisect easier.

Hg bisect returned:

This is likely a duplicate of Bug 760608.

Attachment: workaround

The point of posting this is I think it would be preferable to do this for Aurora rather than backing out bug 729133 completely.

Comment 9

[Bill Gianopoulos [:WG9s]]

This should also fix bug 760608 and bug 760912.

Comment 10

[Patrick McManus [:mcmanus]]

I'll post a real patch for this on monday.
