[nylug-talk] benchmarking iSCSI

[Peter C. Norton]

Put a filesystem on it and run iozone, and also look at the sun
filebench suite. Iozone gives you a good look at the behavior of the
filsystem and IO layer and the caches involved, while filebench lets
you construct microbenchmarks that reflect the usage pattern of the
application(s) you use/will use on the particular system.

In five years we'll make up another plan.
