I installed Zope 2.5.1b2 + CMF1.2 + Plone 0.9.9PR5 <snip> All this on a Pentium 233, 128MB, no swapping. Hardly any other activity on this machine.
If you have a large Data.fs with a lot of products, it is normal to see a long startup time. But if this was a fresh Zope, then I would not expect the startup on your hardware to take more than 15 seconds at the most. There are two possibilities: 1) Your system has a bottleneck you aren't aware of, processes blocking, running out of file descriptors, etc. 2) Python or Zope has some bug w.r.t your system. Here are some questions for you: What is your load average? CPU utilization? Disk activity? Perhaps you could post a 'vmstat 2 10' the system idling vs. starting up zope vs. viewing a page in started up Zope? What OS are you running? IIRC there have been problems with threads on solaris. Did you compile python, zope from source? What version of python are you using? What flags did you compile it with?
During all these attempts, z2.py is in the top of `top`.
I tried to add RAM cache manager, but only Members/index_html shows as cacheable when I try to associate.
This may help, but (a) you have a big problem regardless, and (b) you currently can't associate filsystem-based scripts (i.e. those used in the CMF) with cache managers (something I hope to remedy soon). seb
