Hi folks-
I did crude benchmark comparisons using dd to write to a filesystem mounted
via the pvfsd kernel module. I had just moved from version 1.6.0 to 1.6.2,
and the performance dropped over 90%. Could I be doing something wrong?
Stat of test:
# of iod: 16
# of clients: 64
block size: 65536
count: 2000
I did concurrent writes/reads and timed from start to finish, and then
calculate an aggregate dtr. I know it's a crude test, but it's a
repeatable difference between 1.6.0 and 1.6.2.
Let me know if you have any suggestions.
Jeremy
