Drupal Performance: Solaris vs Linux

I posted final numbers today as to how Drupal 5 performs on a small Sun server, comparing Solaris 10 to SLES 10 (two of the OS offerings available from Sun on this server). The intent of this test was to see how Drupal behaved under increasing load (in this case, Guest hits on the Main Page). I'm pleased to report that Solaris (with the latest CoolStack) appears to provide better throughput, better response time, and lower incidence of 'Server Busy' errors under load.

Let me, at this point, state for the record.. yes, I would have published these results even if the outcome had been the other way 'round. One of the rules we live by in Sun ISV Engineering Open Source is that of transparency. If we set out to test something, it's to determine and share the reality, not the spin. We had a hunch that CoolStack would provide a huge performance improvement, but that was only a hunch. I'm sure that, at some point in the future, we could also find that a well-tuned Drupal-on-LAMP offering meets or beats this Solaris performance - it is, after all, the same hardware.

Lots more Drupal testing to come from from us in the weeks and months to come. Wanna see something in particular? Let us know here or here or right here in the Blog Comments!

I think it's fine that you're willing to also post test results where Solaris is behind. Just please be sure to also go over to opensolaris.org (or Sun internal) and report it as a bug. That's the only way we can get better. I'm looking forward to your next results with a more realistic workload.
