I saved the bugzilla query page to a local file in order to be able to better compare the values. In 2001060713 and 2001060809 the bugzilla query page takes more than 6 seconds to load, whereas Netscape 4.77 loads it in under 2 seconds. That is a huge performance gap.

Sorry, there's some info about my system missing from my bugreport: K6-2-500 with 256MB RAM running Linux 2.4.5

I'm not sure if this has anything to do with it, but I see parts of the banner (the dinosaur head) appear on various parts of the page while it gets rendered. Netscape 4.77 does not do that.

I can see this too on win98 with 0.9.1 -> layout for initial triage

I compared a few other bugzilla result pages and mozilla is consistently faster in loading pages that I save locally beforehand. I regularly see mozilla rendering two dinos in the space where the severity field ends up and below the add CC.
well there should be only one such bug open about this at any time, but i found two, bug 49539 and bug 50411. *** This bug has been marked as a duplicate of 49539 ***

Timeless, please review your duplication of this bug. This bug is about complex forms like the bugzilla query page, bug 49539 talks about huge query _results_. query.cgi is only 68k big. Mozilla does not hang or experience major memory leaks and crash while rendering query.cgi, it is just goddarn slow.
sorry the reporter's last comments were indeed about that bug I picked, but he meant to focus on the query.cgi page, so that leaves bug 46298 and bug 19608. If qa thinks either is a good match that's fine, otherwise reopening. thanks for using bugzilla and contacting me on irc.

linux, build 2001070209 Performance is much improved, no stray lizard heads are rendered on the page, the forms have stopped dancing around the page. Still Netscape 4.77 is twice as fast.

I am running Mozilla on Windows 95 on a Pentium 200 MMX with 64 MB of ram. Mozilla renders _Most_ sites with speed comparable to Netscape 4.x on the same machine, but the Bugzilla Query page is a notable exception. Whenever I load http://bugzilla.mozilla.org/query.cgi in Mozilla, the page starts to render, then ALL my open Mozilla Windows lock for about 8 to 10 seconds, then the page finishes rendering. You know how when you pick a program such as "Browser" or "Mailnews" or whatever, and then it filters down the "component" "Version" and "Target Milestone" Fields? Well, when I do that, Mozilla locks for about 20-30 seconds. If I then go ahead and submit the query, and after browsing the results I return to the query page with the back button, all my Mozilla windows lock up again for about 30-40 seconds. Could I be seeing the same symptom that this bug describes, just horribly amplified by my slow machine? When you change the selected program using Netscape 4.x, the "component" "Version" and "Target Milestone" are filtered down very quickly without blocking the UI at all.

MozillaUser, you are seeing the symptoms of a number of bugs. The first one has been checked into the Bugzilla tree today and should make it to b.m.o. by this week or so, pending approval of 2.14+ by Myk. This is bug 96534; I rewrote the Javascript to make it much faster. You can see the results of the changes by visiting http://landfill.tequilarista.org/bz96534/ (note speed difference in query.cgi and query4.cgi). The other bug you are noticing is bug 97345, which jesup is working hard to get in before 0.9.5. You can check out the patch and progress there as well. If your report is accurate, we should either close this bug, or depend it on the two. There are already perf trackers for Mozilla.

Marking WORKSFORME (this was a dupe of bug 46298 now that I think of it) with the current bugzilla upgrade. Additional perf sould be obtained when bug 97345 lands.

I would say this is still slightly slower, but maybe 10-20%, nowhere near 4 times. ---> VERIFIED
