I created an animated GIF and when I load the page under firefox, the firefox CPU usage goes to 100%. IE does not show that problem.

I am using Firefox/2.0.0.1.

Any idea what the problem could be? Is it a FF problem or a GIF problem?

Thanks

From what I've heard it's not a "problem" at all. Some have said it's a memory leak on Firefox's part but others have said that is how it's supposed to be. From what I understand, supposedly Firefox was designed to use up ALL available/free memory. There's probably others who can explain it better then I can, but that's the short of it. ;)

its a memory issue w/ FF. it isn't (or certainly shouldn't) be designed that way purposely. server applications (web servers, database servers, mail servers etc. ) can and are designed that way -- as they can rightfully expect the full attention of the OS and the hardware. client applications aren't. they must play nicely with others on the same hardware.

what version FF? have latest version?

seen this article? http://www.freerepublic.com/focus/f-bloggers/1327586/posts

There's a big difference between memory usage and cpu usage and never the twain shall meet. You can use up all the memory the system has but still have zero cpu usage. Apparently this animated gif is running at some high speed causing this to happen but I don't know anything about how that would happen.

The GIF is actually quite slow. It has 6 frames, with 6 seconds for each frame.

good call. was typing faster than i was thinking. that said, memory crunch will lead to higher I/O which in turn will hammer the CPU, but still, methinks u r right.
