Hi, Trying to benchmark pvfs running over 10ge. I can run network benchmarks like netperf and iperf and get numbers fairly close to 10Gbits/sec from any client to any of the pvfs servers.
When I try to run some dd's or pvfs2-cp's on the pvfs file system I seem to be reaching a 1Gbit/sec limit: hpca4000(salmr0)60:pvfs2-cp -t -b 4194304 /pvfs2-fs/foo /pvfs2-fs/junk3 Wrote 4194304000 bytes in 49.089332 seconds. 81.484099 MB/seconds hpca4000(salmr0)61:/usr/bin/time -p dd if=/dev/zero of=/pvfs2-fs/foo2 bs=4M count=1000 1000+0 records in 1000+0 records out 4194304000 bytes (4.2 GB) copied, 50.4064 seconds, 83.2 MB/s Is there some hard coded limit with pvfs2 that assumes a 1Gbit/sec link or am I missing something here?
