has anyone tried configuring pyramid / modules / os to run the cached
data directory ( templates, sessions, variables, whatever ) off of a
virtual disk/ram ?
just wondering if anyone has, and if there were decent speed
improvements.

I haven't. One nice thing about Unix based OS's (and maybe Windows
does this, too, I just wouldn't know) is they tend to draft any unused
ram into service as a disk cache, so if you have a small set of
frequently read files, there's a decent chance it will be in RAM.
Obviously, having a ramdisk would give you more control over what's in
RAM at any given moment, but if you provision your server to have a
lot more RAM than it needs for applications, and if you aren't
generally doing a ton of disk IO on a lot of different files that
would cause the cache to turn over frequently, then there's a decent
chance you can just sit back and let the OS take care of it for you.

ah, nice.
i just started thinking about this as I noticed the "pserve --reload"
command refreshing on any change within the directory ( i.e. on Dir/
docs/* -- not on Dir/App or Dir/$env$.ini
The hdd on my macbook is 3-4 years old and pretty full, so it's not
nearly as fast as it should be.
