Low performance on a certain page

more options

There is this page: http://myanimelist.net/animelist/mohas that shows lack of performance specially when scrolling, I first thought it is because of the fixed background, but fixed backgrounds are OK in other sites. Is this normal? It would be great if I at least knew what is wrong with it.

Thank you

This page is the same for me too.

I think it maybe be either because the page is too long or that there is a lot CSS and Javascript codes to load and run.

I'm not sure how you could fix this.

I went to the page. I had no problem with it. Nice background.

Also when returning to the page after a while (the page is open in the browser, I just spend some time on another website in another tab) the fixed background seems to be redrawn this takes about 1 second and contributes to the slowness, does firefox have a kind of resource monitor to see a page resources (memory, processor, threads etc.)?

Give this a try;

Clear the Cache Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

and

Remove Cookies Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

If there is still a problem, Start Firefox in Safe Mode While you are in safe mode; Firefox Options > Advanced > General. Look for and turn off Use Hardware Acceleration.

Disabling hardware acceleration solved performance issue, but I cant keep it disabled, any idea why this happens?

Leave hardware acceleration disabled.
From Mozilla.org help files;

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Does it help if you run this code in the Web Console (Firefox/Tools > Web Developer;Ctrl+Shift+K)?

javascript:void(document.body.style.setProperty("background-attachment","scroll","important"));

You can use this bookmarklet code as the location in a new bookmark and use it when necessary.

Thank you core-el that didn't help unfortunately

I am a website designer and I can't really see any issues with this page, besides the fact that it is twice the size of an average website.

The tables should be split up into separate pages or something to decrease the lines of code.
