Hi,

	i write to tell you that zope can do much better but even
much worser. the site www.tradinglab.com is powered by 4 netfinity
and each of them is capable to handle about 150000 hits a day for
a total of 600000+ hits. we use a modified kernel (see the linux
virtual server pages, www.linux-vs.org) and apache+zope.

	the "worse" part is that the 2 biprocessor machines rate
really bad when compared with the monoprocessor ones. and under
a heavy load zope does much better when forced to use only 1 or 2 
threads. with more threads it just lock. the problem is more evident
on the 2-processor box, maybe evidentiating a deadlock problen.

	if you want better statistics i can post to this list the
webalizer generated html pages.

ciao,
federico
