Hello everybody, I'm posting this message because I'm quiet frustrated.
We just bought a software from a small software vendor. In the beginning he hosted our application on a small server at his office. I think it was a Fujitsu-Siemens x86 running debian Linux. The performance of the DSL-Line was very poor, so we decided to buy an own machine to host the application ourselves. The application is based on the Zope Application server (2.8.8-final w/ python 2.3.6) along with many other packages like ghostview, postgres, freetype, python imaging lib, etc... I once saw the application running at the office of my software vendor and it was running very well. So I thought that - when the bottleneck of poor DSL performance has disappeared - the software will run as fast as at his office. But I erred. The performance is more than poor. We have a Sun T1000 with 8 cores and 8 GB of RAM. First, I installed Solaris 10 because I know this OS better than Debian Linux. Result: poor Performance. After that I decided to migrate to debian: [EMAIL PROTECTED] > uname -a Linux carmanager 2.6.18-5-sparc64-smp #1 SMP Wed Oct 3 04:16:38 UTC 2007 sparc64 GNU/Linux Result: Almost even worse. The application is not scaling at all. Every time you start a request it is hanging around on one cpu and is devouring it at about 90-100% load. The other 31 CPUs which are shown in "mpstat" are bored at 0% load. If anybody needs further information about installed packages, I'll post it here. Any hints are appreciated! Thanks, Joe. PS: Fortunately the Sun is not bought yet. It's a "try&buy" from my local dealer. So if there are any hints like "buy a new machine because Sun is crap" I will _not_ refuse obediance. -- http://mail.python.org/mailman/listinfo/python-list
