Expected Results: Smooth constant running much like I get from Opera. MD 7.2 PII 450 64mb ram 128 mb swap

I'm not experiencing this problem at all in mozilla 080608 linux build. I'm also not experiencing this with 0.9.3.

I was using it again last night and it has to be mozilla although I should not have said surfing in my original post but changing windows or desktops or start up say Konqueror to access a directory. Last night about half an hour in things just got so slow that on shutting down mozilla and starting Opera things got better, Opera started in twice the time it normally takes but the system responded a lot better. To get the system back to normal I had to log out and log back in.

Not seeing it on Win2k with 0.9.3 However, my experience is that Moz easily eats 40 megs of ram or more with 3 windows open and after surfing even for a very short while. The jerkiness/slowness is probably your system doing lots of swapping, since you only have 64 megs of ram. Try stuffing some more memory in your machine and see if the problem continues to exist (Hey, memory is cheap these days :)).

Marking NEW.

Ok I have upgraded to 192 Mbs from 64 and so far for the past day Mozilla seems fine. I guess its not so much a bug but a system requirement that mozilla needs probably 128Mb's ram to run smothly much like Netscape does. O' well she's a memory hog. Thanks for your help.

marking worksforme after reporters comment. Reporter: We know that mozilla use many RAM and we try to fix that....
