The page www.aftonbladet.se is using way to much CPU and is like 20x slower then netscape 4.75. Also scrolling is really slow here while it was smooth on NS4.75. Most (all?) other pages are fast and slick. And this page is not very big, so it probably should be considered a bug. Sorry, but I have no other information.
Reporter, the page loads just fine (much faster than 4.75) for me. Could you please provide more information on the build you are using? Also, please read the bug writing guidelines at http://www.mozilla.org/quality/bug-writing-guidelines.html Thanks for using Mozilla and reporting bugs!
Also, please provide CPU info (type and MHz), which could be a factor. On a p3/500 RH6.2/Gnome box, i can't say i noticed any difference in time, only in what renders first: Mozilla lays out the text much faster than NC, but overall download/layout time seems about identical. If you use a new build, can you test this again? I suspect it may have been due to some temporary external network hickup.
I'm using the M18 release packed by readhat (mozilla-M18-4) on a PII-400 RH6.2 Gnome, everything up to date. And it's almost only this page that is slow. Mozilla says it's Build ID 2000101815. It could be that you use the latest cvs version of mozilla, and it's already fixed. Sorry for reporting it in that case. I'm 100% sure that it's not the network connection. I have a fairly fast connection and I read that site every day. If I load it 10 times with mozilla and 10 times with NS4.75 it is much, much slower all 10 times on mozilla. It is something that is different with this page compared to every other page I use. I could try to get a new build. For the moment I cant build mozilla since I've change some parts of gcc (but i'll change that back soon anyway). If I can find a prebuilt version that works and then I'll try it out as fast as possible. It takes about 1 minute with 100% CPU before the page is finaly loaded. It's nowhere near that time with ns4.75.
Not seeing this on Windows2000 with latest build (2000110904) on a P1-225 with only 80MB RAM: Loading time NS475: about 25 seconds Loading time Mozilla: 39 seconds (probably because of swapping on my machine)
I could also say that I have 256 megs of RAM so there was no swapping. I still use XFree86 3.3.6 (it's a RH6.2 box). I just loaded the page again and it took 62 seconds. The text is rendered really fast. With ns4.75 it takes maybe 4 seconds to load the page (thats everything, including pictures). I also noted that after the page is loaded X is using 50% CPU all the time. I guess that there is something strange with the animated pictures. But I have no problems with animated pictures on other pages.. So my guess is that there is something with images and XFree86 3.3.6.
Making summary more specific.
Summary: 20x slower then netscape 4.75 → Specific web page loads 20x slower then netscape 4.75
whatever this was, it appears to be fixed. I see no exessive CPU usage there with the latest build. If you wish to try a recent build: The very latest is found at http://ftp.mozilla.org/pub/mozilla/nightly/latest There are three different precompiled builds available. If you have root access and wish to install, you can for instance grab mozilla-i686-pc-linux-gnu-sea.tar.gz (Right-click and "save file as") -uninstall previous installations -tar -zxvf the tar.gz you downloaded -cd mozilla-installer -as root run ./mozilla installer To initialize registration of installed files, you must start mozilla once as root, before as a normal user. Mozilla will actually start immediately after installation. (Also run mailnews once if you install that, but no need to create a root mail-account. Just quit after mailnews also has started, log out as root, and regular users should also be in business. The slowness you observe while scrolling may be caused by the animated gif's, but think you'll find the behaviour to have improved. If you test a new build, please comment about both download time as well as scrolling performance.
This page loads at the same speed or even quicker with Mozilla. Tested on build (2000110721) on linux.Reporter, please reopen the bug if you still have problems after installing a current build, and take into account that the page have tables and can take a little more proccesing that can slow the rendering if you got a slow proccesor.

I downloaded and tried build 2000111221 and it is a little bit faster. Before over 60 seconds and now 23 seconds. 3x better. But its still 5x slower then ns4.75 and it is still using 50% CPU on my PII-400 after it have loaded the page. When I run top, it's X that is using 50% CPU, but it's mozilla that is causing it. The old ns4.75 is using almost no CPU after the page have loaded. CPU usage for X is about 1 percent. This might be a factor that makes the page load slower also. And the old ns4.75 is also doing the animation. So I have not turned it of or anything. The pages looks more or less the same. Some small layout difference, but no error.

I tried some more. 1. Start mozilla (build 2000111221) 2. Go to www.aftonbladet.se (tock 15 seconds this time, someting cached I guess) 3. CPU usage is about 50%. I've made a screenshot here http://zigo.dhs.org/~dennis/2000_11_13_090651_shot.jpg 4. Klick on one of the articles 5. Klick back to go back to the start page Now the CPU usage is low and normal http://zigo.dhs.org/~dennis/2000_11_13_090927_shot.jpg In the screenshots you can see my CPU meter in the gnome-panel. In the first there are big spikes very periodicly. And in the second shoot there is very small spikes but with the same frequency. It's just my guess that this have to do with the animated images, but what else could it be. Very strange, isn't it.. The DNS i use have been quite bad the last days going up and down, so here is the links with IP adresses instead. I hope www.granitecanyon.com will fix their DNS servers soon. http://184.108.40.206/~dennis/2000_11_13_090651_shot.jpg http://220.127.116.11/~dennis/2000_11_13_090927_shot.jpg

Worksforme, seems reasonably fast, didn't do any comparing but the page shows no obvious sighns of a problem in mozilla, but then again the site probably changes daily so who knows...
