Number of files in a directory / performance

[keith smith]

Thanks for your reply!

...more than a few thousand files

I don't think I'll have a problem for a while!

Thanks,
Keith

Depends on the filesystem and the utillities. I think shells and ext2
still don't do well with more than a few thousand files in a single
directory. Haven't tested it in a while. I don't know if ext3 might have
the same type of issues.

reiser should handle that type of situation just fine.

apache should handle it fine as well.

If some of those pages are including files from the full directories,
there might be an issue. I would think PHP, Perl, Jave, etc. should be
able to handle that fine, though.

ciao,
