Firefox: how to improve mem usage
74
Even after at least hundreds of posts on digg.com, even after a Slashdot article there’s thousands of people out there complaining about the Firefox Memory Bug. Lets get it straight. It’s not a bug. It’s part of the cache feature. This ‘feature’ is how the pages are cached in a tabbed environment. To improve performance when navigating (studies show that 39% of all page navigations are renavigations to pages visited less than 10 pages ago, usually using the back button), Firefox 1.5 implements a Back-Forward cache that retains the rendered document for the last five session history entries for each tab. This is a lot of data. If you have a lot of tabs, Firefox’s memory usage can climb dramatically. It’s a trade-off. What you get out of it is faster performance as you navigate the web.

Thanks for that information I can use it
TRY THIS: I was testing this on my 3ghz cpu, 2gb ram, HP machine. I have been noticing this incredible lag for days when using FF. So I did some testing. When I am using FF I always have my gmail open and an igoogle page. Those are two tabs that are essential for me. Well, what I found was that when I was using the NEWEST version of GMAIL my CPU usage was hitting 50% plus pretty consistently and the MEM usage ranged from 105k to 210k. BUT when I switched to the OLDER version of GMAIL and left it open my CPU usage bottomed out and only spiked when I opened new tabs or emails in GMAIL. MEM usage stayed around 120k pretty consistently as well without ranging too much in the upper register. I can't believe that Gmail is such a culprit in this little affair though. I'm surfing much smoother now. Give it a try. Try switching from the newer and older versions of gmail with the task manager opened. you'll see a crazy difference.
