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.
