Testing AFP with Bonnie++

I'm looking to implement an iSCSI-based backend storage system for our next server rollout this summer. I want to gather some benchmarking data to compare how the new setup would perform compared to the current one. My plan is to use Bonnie++ to test our current network fileshares, but I'm running into problems. I can compile Bonnie++ using Macports and run it on the local filesystem, but when I try to run a small test on a AFP share, Bonnie++ reports: [code] $ /opt/local/bin/bonnie++ -s 10M -d [AFP share] Writing a byte at a time...done Writing intelligently...done Rewriting...done Reading a byte at a time...done Reading intelligently...done start 'em...done...done...done...done...done... Create files in sequential order...done. Stat files in sequential order...done. Delete files in sequential order...Bonnie: drastic I/O error (rmdir): Directory not empty Cleaning up test directory after error. [/code] Has anyone been able to use Bonnie++ to test their network filesystems? Here are some notes: 1. Bonnie, the original version from the 1990s works fine on the AFP shares, but doesn't have as robust a feature set 2. I tried testing on an AFP share that was world-writeable, so no permissions issues 3. Can't find any errors in the logs on either server or client 4. Current system is a 10.5.6 G5 Xserve with an XRAID Any help is appreciated, as well as other ideas for benchmarking/testing. thanks!
