[Asterisk-Users] Asterisk & MySQL Blobs

[Paul Traue, Jr.]

In ReiserFS3, the performance loss for a directory containing 10's of 
thousands of files is negligible.  I've personally had directories with 
70,000+ files in them, and the performance has been stellar.  Most 
traditional unix file systems break down around 5k-10k files, but I'd 
trust ReiserFS with more than 100k in a single directory.
