This depends on the filesystem, not on the architecture.
However, if you've got that many entries, it would be better to
implement a different scheme for storing files in the disk cache.
Right now, an entry in the disk cache is in the file
<domain name>/<sha1 hash of the URL>
The advantage is that it is easy to remove all files for a given site
(rm -r), and that you've got good locality (all files for a single
cache are kept together, so the directory will be in cache most of the
time). However, as you noticed, it doesn't scale well.
It would be a good idea, for very large proxies, to use something like
<domain name>/<first digit of sha1>/<sha1>
which will obviously be suboptimal for small proxies. I guess I'll
implement it and make it optional.
