56624 - needs a lot of time to load the page

Status: VERIFIED WORKSFORME

(Core :: DOM: HTML Parser, defect, P2)

Description

[serge]

M18 needs a lot of time to load http://ntv.ru. Mozilla hangs in long time and
shows the page only after this. Nightly build from 20.09 does this much more
faster.

Comment 1

[Fabian Guisset]

confirmed on win95 build 2000101320.
Absolutely no idea what's up here. It might be due to the strange(?) alphabet
used, (cyrillic?), or simply bad html.

Confirming on Windows 2000 Build 2000101320/trunk
It seems that mozilla hangs a short time on page load.

Comment 3

[Doron Rosenberg (IBM)]

the page has catastrophic html
(http://validator.w3.org/check?uri=http%3A%2F%2Fntv.ru%2Findex.html
)

not sure where this goes (layout?)

[Asa Dotzler [:asa]]

Comment 8

[harishd]

Parser performace work, which will be landing soon, should fix this problem.

Comment 9

[Azrael AOD]

Bug 61842 has been marked as a duplicate of this one, due to poor parser
performance, in verifying it I am noting down here that any fixes should also be
cross referenced against the details in bug 61842 before verified, thanks.

I'm sure the performace bug is fixed. I's trying to verify it but crashed 
with the following trace ( 12/20/00 & 12/22/00):

I'm still seeing the crash. Giving bug to buster.

[buster]

I'm looking into this.

Comment 14

[bsharma]

updated qa contact.

Comment 15

[Christopher Hoess (gone)]

Crash dependency closed. Page doesn't hang, seems to close in reasonable time. 
Closing WORKSFORME.  Please reopen if you still feel performance is substandard
with regard to comparable pages.

Comment 16

[Kevin McCluskey (gone)]

Build reassigning Buster's bugs to Marc.

Comment 17

[Kevin McCluskey (gone)]

Resolving as WFM.
