Hello , my question is a bit complex ( for me ). I have : - Linux RH 6.1 - python 1.5.2 --with-thread (source compiled) - zope 2.2.x or zope 2.3.x (source compiled) In any program in python with Linux (inclusive Zope), the threads are processes,i.e, they consume memory and don´t share it. In Windows this is different. In Linux, I have Zope running with 4 Threads. I have five processes and everyone consuming about 12 MB => 12 * 5 MB = 60 MB In Windows in the same situation I only have one process and the threads share the memory, which is the most desirable situation. Why?? Does anybody know a solution for Linux, in order to have only one process and threads sharing memory, as in Windows?? Thanks.
