For a great presentation on how Solaris 10 and DTrace helped Twitter improve their performance by 15% see Adam Levanthal's most recent blog entry along with his presentation provided at OSCON.
In this case, the application was written in Ruby and the DTrace provider in Ruby really helped.
Why should you care?
If you are building a fast growing company (as Twitter is) it's inevitable that you will run into performance issues. Solaris 10 and Dtrace provide the kind of visibility into your application's performance that can help you grow smoothly.
Solaris has been receiving EAL4 evaluations against the Controlled Access Protection Profile (CAPP) since the Solaris 2.5 days. With Solaris 8 we added the RBAC PP. To the best of my knowledge the Linux variants (RHAT 4 and Suse) have only recently (2006) received EAL 4 evaluations. We were the first to have a multi-level OS with TSOL 2.5 and some versions of SunOS 4. (aka Solaris 1.X) Several versions of Trusted Solaris (2.5. 2.6, 8) have received EAL4 evaluations including the LSPP. No Linux or MS Windows variant has ever received this evaluation yet.
