A while back, someone put a tip on the Gentoo forums for making Firefox store its cache in RAM rather than on the disk. It's a hack that basically mounts a ramdisk where Firefox stores the user profile. I haven't seen any benchmarks, but it seems like a good idea and I find the performance pretty good. This is especially appealing for netbooks that use flash storage instead of a hard disk.
