[Gluster-users] GlusterFS performance with small files.

[Haris Zukanovic]

Is there anything to do to optimize the read for small files in a 
replicated gluster setup? The files reside allready on the server in 
question in the brick.
Something like disable diverse checking for files that I know are not 
updated often? For example web files like images uploaded through the 
CMS. These files are uploaded once and never modified again...

kind regards
Haris
