[Gluster-devel] glusterfs as root filesystem

I was fetching a single file with wget. I tried this with small (a few kb)
and larger (several MB) files and got the same results: a wget from local
disk took about .001 seconds and a wget to glusterfs took .14 seconds. Is
this a valid way to test?

Sort of. I did use that but I could never get it to actually cache anything.
My reads never got quicker than the first one, no matter many times I called
the same files... But specifically I've heard talk from people asking about
using local storage for caching, which is not supported under the io-cache
translator. So I would use that if it became available, and if not, I'll
eventually have to figure out why io-cache isn't working.
On what files were you not getting the speedup? on executables? or others?
if one shot of activity was exceeding the default cache-size value (32M)
then you may have to tune your priority and cache-size parameters to get any
It always takes longer than you expect, even when you take into account
