Description Martijn Wargers [:mwargers] (not working for Mozilla) 2006-11-21 03:01:09 PST
I was hoping that I could find a possible regression in performance for bug 360789, but I didn't see that.
But I see with the testcase that I made a performance regression when cairo was turned on on windows.
So that's why I'm filing this bug. It might not be the most useful testcase, but it's probably useful to keep track of it, to ensure that the performance will turn back into pre-cairo days.

You need to download the testcase locally to get a good working testcase.
In the statusbar, I get the following results:
2006-02-22 build: 17391ms 
2006-02-25 build: 23735ms 
That is the period when cairo was turned on in windows.

2006-11-20 build: 21000ms
2006-11-20 branch build: 19484ms
Not as noticeable a difference, but still. (It's better to test with a non-cairo trunk build).
Comment 2 Martijn Wargers [:mwargers] (not working for Mozilla) 2008-06-11 14:52:17 PDT
Current trunk gives 28577ms
A branch build gives 24510ms
So there is still a performance regression visible here.
Note that trunk doesn't show the iframe big anymore (because of some CSS rule), so that should be a reason to be even quicker than branch, perhaps.

I don't think this would block 1.9.1.  Please re-nom if you disagree.
Comment 4 Vladimir Vukicevic [:vlad] [:vladv] 2008-07-22 13:53:28 PDT
There's a border involved here, so that's almost certinly it; could get faster with an upcoming patch to borders.
Comment 5 Vladimir Vukicevic [:vlad] [:vladv] 2008-07-22 13:57:32 PDT
Yeah; Fx 3: 24322 with border patch: 23020.  Will land that when the tree reopens.
Comment 6 Mike Shaver (:shaver -- probably not reading bugmail closely) 2010-11-02 23:48:41 PDT
I think vlad landed it, though borders have continued to plague is well into the year 2010!
