Mozilla hunting for memory
Christopher Blizzard, a member of Mozilla's board plans to lower the memory use of Firefox. The browser is suffering from significant performance problems, where it used to be one of the fastest browsers it has become one of the slower ones. Mozilla developer Stuart Parmenter is researching the matter.
Parmenter found out that Firefox has a lot of caches internally for performance reasons. These
include things like the back/forward cache (helps speed up
loading pages when you hit back), the image cache (keeps images in
memory to help load them faster), font cache, textrun cache,
etc. The lately introduced cycle collector Gecko 1.9 which avoids cycles in XPCOM objects and the JS
garbage collector also require a lot of memory.
Parmenter concludes that all of these things mean Mozilla could be keeping objects that could be taking up space and they need to be eliminated. He released the RAMBack extension which clears most of these things.
