I compiled Zope 2-3-0 from source on a Pentium II 266 MHz with 128 MB RAM on Redhat 6.2 and it runs very slowly. When I say slow I mean it takes approximately 3 minutes to start up and 5 seconds per request. I'll give a bit more background since I don't think this is a Zope problem per se. This is not a first Zope install - on our public server I frequently compile Zope from source and it flies. On this particular server almost everything was compiled from scratch (kernel, apache, python, etc) with aggresive optimization turned on. All the software installed is really running smoothly except for Zope. I then recompiled python with no optimization but still Zope was crawling. It took me quite a while to build the server thus far and it took a lot of effort securing and optimizing it but at the moment I really don't have a clue where to start looking for the problem. What is funny is that other python-built software like mailman is running up to speed but mailman is not multi-threaded or nearly as complex as Zope. It seems to me that accessing the Data.fs file is problematic, because the harddrive just seems too busy compared to other Zope installations we've made. The load on the CPU seems normal. Any pointers would really be appreciated. Roché
