Tuning the Firefox prerendering cache!

[Floid]

Of interest to... probably everyone, TheInq unveils the heretefore undocumented knob.  For 1.5, at least.

See the blog entry directly for a muddled discussion of specifics.

Note that this system probably works great on systems with fast swap, and horribly on those without (contrast throughput from a modern 80GB+ disk with its own 8MB prefetch cache to the old 2GB Barracuda I use to avoid OOM-kills on my FreeBSD box).  Pessimizing the prerendered caching will result in rerendering from cached HTML/image objects/etc, which moves the load from the disk to the CPU (where you might've expected it),

Lots of discussion of other leakiness and so on in the comments.

I think part of the leaks on *NIX may be related to X server behavior (and possibly SysV IPC), but I haven't done much analysis in a while.
