[Zope] How can i improve performance of website under heavy load in Zope2.6.1

[Marco Bizzarri]

1) improve the number of object in the cache: the default is 400 which
is incredibly low for a normal site; put it to 5000 and check;

2) (if possible) upgrade to a newer release of Zope, namely 2.8, which
removes many possible conflict, and therefore improves response time;

3) install a Zope/ZEO configuration, with more than one Zope server
responding; don't mix too much with threads which is, as far as I
know, tricky stuff; use more than one physical server, running Zope,
connected to a ZEO backend; distribute the load using whatever load
balancer of your choice;

4) review your application needs; check what are the actual
bottlenecks; is there any static content you could better serve using
apache (like images, documents..) ?

5) make a google search with "improving Zope performance" ;)

Marco
