Migrating systems to 2.9.0, we have noticed "sluggish" behavior compared to 2.8.4. The 2.8.4 systems run on a dual processor AMD2600 32-bit processors. The 2.9.0 systems run on AMD dual opteron 240 processors. The dual opteron systems have much more memory, much faster memory, and faster disks.
We use mysql and pound and a number of other systems. I am trying to localize and quantify the performance issue we are seeing. I have checked the raw hardware as seen by python: 2.9.0 machine: Pystone(1.1) time for 50000 passes = 1.07 This machine benchmarks at 46729 pystones/second 2.8.4 machine: Pystone(1.1) time for 50000 passes = 1.23 This machine benchmarks at 40650.4 pystones/second Running disk benchmarks suggests that the 2.9.0 machine is faster in disk operations by 10 to 20 percent. I have not yet checked raw network operations yet, but I suspect that they show equivalent performance. I believe that Zopes are working fine and that the performance problems we are seeing are in the management of network input and output rather than in the Zopes themselves. Is there some performance test I can use to characterize the Zope system itself so I can compare Zopes running on the two machines? _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
