RE: [Zope] Zope slow if left unused for hours

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.

Sorry for the delayed response. I would recommend asking / CC'ing the list, so that you get the benefit of the whole community's experience. I have CC'ed the list. WRT to your question: I don't know of any off-the-shelf way to do what you ask. We have built solutions for such problems based around syndicating RSS from "spoke" sites to a "hub" site, but the software isn't part of any freely-available offering.

Hiding header?
by Shane Graber 05 Jan '05

05 Jan '05

Is it possible to hide the header that Zope advertises? Currently, Zope is advertising "Server: Zope/(Zope 2.7.3-0, python 2.3.4, linux2) ZServer/1.1 Plone/2.0.5", that is forwarded as is by Apache. I know that apache can be set to hide its current version. It would be nice if we could do the same with Zope. Is this possible? Where/how do we do it? Shane

Hiya, I'd like to ask all ZSyncer users to please try out ZSyncer 0.6.1-beta2 if you can. It's on sourceforge at: http://sourceforge.net/project/showfiles.php?group_id=28073 This release fixes or obviates all bugs I know about. I need some field testing before releasing 0.6.1-final which I would like to be very stable and usable. Thanks! -- Paul Winkler http://www.slinkp.com

The server slows to a crawl and Zope will eventually stop serving pages. I've been watching the debug page in the control panel and the refcounts fluctuate up and down by small amounts but the trend is always up. They never seem to level off, they always climb. Is this typical or does this suggest a problem? I wrote a new test script in /usr/lib/Zope-2.7/lib/python/Products/Transience/tests that creates sessions with large arrays of random data. Running this test did not seem to cause any leaks. However, if I uses sessions in Zope, Zope seems to leak. The larger my session data the faster it leaks.
