[Zope] Re: Threading, dtml and performance?!

[Paz]

Oliver,

I'm a bit confused. What version of things are you running? I remember
that this thread changed quickly to specify Solaris with the problem. I
tested this problem on my linux box (note, dual processor) without any
problems at all.... Mind you of course it slowed the response down a
bit, but it was stable...

And what is the significance of 2 methods and 'not 4'?

As I wrote before, it happens in mod_perl, it doesn't happen in
zope2.3.3 on

linux 2.2.13.
And I would still be interested in an explanation why two long running 
methods (not four) seem to be able to stall zopes http server on linux.


cheers,
oliver
