XFS performance tracking and regression monitoring

[Mark Goodwin <markgw@sgi.com>]

We're about to deploy a system+jbod dedicated for performance
regression tracking. The idea is to build the XFS dev branch
nightly, run a bunch of self contained benchmarks, and generate
a progressive daily report - date on the X-axis, with (perhaps)
wallclock runtime on the y-axis.

The aim is to track relative XFS performance on a daily basis
for various workloads on identical h/w. If each workload runs for
approx the same duration, the reports can all share the same
generic y-axis. THe long term trend should have a positive
gradient. Regressions can be date correlated with commits.

Comments, benchmark suggestions? ANyone already running this?
Know of a test harness and/or report generator? Or will we
just roll our own - seems conceptually fairly simple.

Thanks
