WIYF (http://en.wikipedia.org/wiki/Ext2#File_system_limits):

"If the number of files in a directory exceeds 10000 to 15000 files, the 
user will normally be warned that operations can last for a long time 
unless directory indexing is enabled. The theoretical limit on the 

relevant for practical situations."

You may also want to check out info on the tune2fs utility, which I'd 
expect the thing to use if you wanted to enable directory indexing. But 
of course you'd need full control over the file system for that, so if 
your shop is hosted on a shared server, you may be out of luck.

I think the main problem with those is that other file systems don't 
have them. They're a pretty neat idea to tag files with additional 
information.
