[Gluster-users] glusterfs alternative ? :P

[Keith Freedman]

what I'm noticing is, with AFR/HA in gluster it seems that in the 
general case, 1.3 seems overall faster from a user experience perspective.
2.0 is a bit more robust and with that robustness seems to come a 
slight performance problem.

when you do your benchmarking do so with some very large directories 
and some small ones, and some which change rapidly and some which 
change infrequently.

it'll be interesting to see how that impacts things..  In my 
empirical observations, a large directory has a large impact in 2.0.

it's entirely possible most of the performance related items I've 
notices are resolved, I'll need more time to see how things behave.
