Poll - Large ECC 6.0 system on Linux

Hello,

We are analyzing the option of switching from Windows 2008/Oracle platform on Linux and we would like to know if there are large ECC 6.0 systems productive on Linux? We have regularly more than 5000 concurrent users in a system with a consistent .5 seconds response time.

Could you please state the Linux distribution and DB that you are using and the size of productions system.

Thank you in advance for your help.
