Isilon and iozone
I am a beginner with iozone and still pretty new with isilon. The numbers I'm getting back from iozone seem pretty high when reading/writing to the Isilon from iozone in OS X. Here is the command I'm using:
./iozone -a -i 0 -i 1 -I -f /Volumes/ifs/iozone/iozonetest
(I include the '-I' flag so it does not use cache)
My results are in the 2 GB/sec+ range using a machine with only a 1 Gb connection. The speeds returned by iozone are in KB/sec, right? Here are my results...

As I look at the isilon statistics it definitely is not going this high. Any thoughts?
