Scavenging the mail folder uncovered Aitor Grajal Crespo's letter:
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.
this is completely wrong. threads under linux have a different pid but are created setting the CLONE flag so they share almost anything (address space, shared objects, etc.)
In Linux, I have Zope running with 4 Threads. I have five processes and everyone consuming about 12 MB => 12 * 5 MB = 60 MB
this is what top tell you, but try using memstat to show the real memory consumed by each process... ciao, federico -- Federico Di Gregorio MIXAD LIVE Chief of Research & Technology fog@mixadlive.com Debian GNU/Linux Developer & Italian Press Contact fog@debian.org All programmers are optimists. -- Frederick P.
