Orion Performance

429720Dec 17 2008 — edited Feb 4 2009

I am using Orion as a load generator for storage on several 64-bit Linux boxes and am finding that for large sequential reads, Orion seems to be the bottleneck. I am generally not able to pull more than ~1500MB/s with one Orion process consuming 100% CPU. If I run several Orion processes concurrently, I can peak ~3600MB/s. There does not seem to be an easy way to synchonize multiple runs and consolidate results. Does anyone have suggestions to improve the situation? Also, does anyone know a means to contact the developers for comment and/or and enhancement request?

Running version 11.1.0.7.0

Command line below:
/usr/local/bin/orion -matrix basic -run advanced -testname ori_RAW -duration 60 -num_disks 8 -write 0 -cache_size 0 -simulate raid0 -stripe 1024 -verbose -type seq -num_streamIO 8

I have tried adjusting num_disks, stripte, and num_streamIO with no meaningful change in results.
