That was the old conventional wisdom, but these days people find 1GB caches useful (especially since the cache was reorganized to not be flat). Meanwhile, 128MB will thrash a lot. It *does* depend on usage to some extent, but for home directories you should almost always have a fairly large cache.

Last time I checked, any time Firefox loads images or media for a page, they are loaded into the cache and (dis)played from there. There used to be a memory cache once, but not at this (URL) level any more. You really want this to be local, and maybe even ramdisk. -- brandon s allbery allber...@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
