This is because the first time you make a request to your Zope instance, it retrieves lots of objects from the ZODB (file). For subsequent requests, most of this objects are cached in a connection object cache. See your /Control_Panel/Database/manage_workspace, select a database, and then have a look at the Cache Parameters tab. There is one cache per connection, and usually there are 4 connections to the ZODB. But in general, under reasonable load on your site, the cache should be efficient. I don't know of any way of optimizing this. Hope this helps.

The first time I hit the site (even the ZMI) the first page takes a long time to load; everything after that is speedy. I'm thinking it's some sort of caching issue but I'm not sure where to look to remedy the probelm. I am not running debug mode either.
