Well, not to pull rank or undermine a colleague, but I don't think Sid knows the code like I do. Go look at stripe_writev if you want to see how it will issue multiple requests within a loop xlators/cluster/stripe/src/stripe.c:3754 before waiting for any to return. You can even use gdb to step through it if you still don't believe me. > Writes are handled one brick at a time.

I agree on "should" but there are other explanations besides lack of parallelism. Please note that diverting people to the wrong place keeps them from fixing anything in the right place. _______________________________________________ Gluster-users mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-users
