I think you are on to something. My site has grown way bigger than I ever
expected and my docroot is now over 4000 user/directories
So now I have to figure out how to set up my apache(another mailing list) to
help me split these out
Thanks
Randy

Subject: Re: What are people doing for data sharing between real servers
Are you hashing your directories? My read/write speeds dropped through the
floor when I didn't notice PHP wasn't cleaning up session files after
itself. The problem was I had a couple of million session files in a single
directory. I now run a script that nukes old session files and my speeds are
more than adequate.
If you have more than a thousand files in a single directory that could be a
huge problem. The solution I like to use is to hash directories based on
file name:
foobar.jpg -> /images/fo/ba/foobar.jpg (using substr() for instance).
That way you break up images across multiple directories.
