RE: [Zope] how to test connection speed on external zope server
Also worth mentioning, if you were testing caching performance, you would also want to have 2 laptops running a tool like this, have one start a test, delay a little bit, and let another start after you feel confident that the cache is relatively full of the items you want. This sort of testing would apply just as much to Apache/mod_proxy (assuming you cache) as it would to Squid.

Worth testing, also, perhaps is caching performance for any caching proxy server you put in front of Zope... (For example, if you have a ZEO cluster of 2 boxes, you could set up Squid to run with no caching, doing plain old proxying, and see what kind of performance you get round-robining your two Zope servers, then you could turn on caching, run tests with default refresh patterns, and compare; finally, you could tweak caching via refresh patterns, HTTP headers in your applications, and HTTP cache manager tweaks in Zope and run more rounds of the same test).

You may want to start by using ethereal or similar to see what's going from / to your Zope server. Especially be on the lookout for lots of unnecessary forward (and possibly reverse) DNS lookups from your Zope server to your (or ISPs) DNS servers. Sometimes all you need to do to improve response time is make sure all your apache virtual hosts are listed in your server's /etc/hosts file :-) Adam
