[Linux-cluster] data journaling for increased performance

has anyone been able to use GFS data journaling to get any measurable 
performance boost? For those unfamiliar:


We have a 2.6 TB maildir mail store (e.g. lots of small files) and think 
of implementing it (we will take any performance increase we can get as 
long as it does not impact reliability), and even though it will only 
apply to new files.

Also, is it possible to check if the inherit_jdata (for directories) or 
jdata (for files) flag has been set?
