Re: [Zope] Unexplained Slowdown
Hi all, Thanks for this file! Yesterday I thought I'd lost it, altough I heard more rumours of 'slowdown' I couldn't find a solution for my problem since I gave that demo and zope was so slow... you should have seen my face at that moment (completely red!). I tried everything, reinstallation of zope and interbase drivers, etc... My last resort was going to an earlier version of zope, or trying to use pcgi, but this morning I found this patch in my mailbox. I tried it and.. nice! All problems were gone. So, now I can give the demo again and zope will be fast again :-)! Regards, Tom ps. Can you give more information on this? ie something more than the lines below. It seems an interesting case. - Original Message - From: "Brian Lloyd" [EMAIL PROTECTED] To: "Ian Thomas" [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Wednesday, January 17, 2001 10:10 PM Subject: RE: [Zope] Unexplained Slowdown This is due to an ill-fated attempt to make 'domain-based authentication' less expensive (but that backfired to some extent because it can make non domain-based auth more expensive, especially if reverse DNS lookups are slow for you).

Some background. 1) I am a computer teacher teaching Zope to my second year web development students who have already learned HTML and been introduced to JavaScript. 2) The server is a my test machine that my students and I use for learning. 3) The "production" server still running 2.2.4 continues to preform normally. 4) The machine is Celeron 500 mhz 64 meg ram running Windows 2000 Server 5) I run Medusa server that comes with Zope to server the web pages. 6) There is no gateway set up on this machine so that it is only visible from within the school. Notes. 1) It is much faster if I access via localhost on the server. What I have tried. 1) Installing 2.2.4 on another port. It ran just as slow. 2) Today I removed the 2.2.4 installation and installed 2.3beta, again it seems just as slow. What Next? The next thing I was thinking was to serve the webpages from IIS using PCGI. I am interested in other ideas. I.

Re: [Zope] Unexplained Slowdown
Forgive my enthousiastic comment in my previous message! Some more news: The overall response is better than before, but sometimes Zope (or ZServer) is very slow. This slowdown is at my Linux Server and at my Win Clients (NT 4 sp5) It takes 1-2 minutes before I even get the log-on screen (on my server!) to enter zope. I don't know where this is comming from, but it is strange. Overall, the response is better than before, but some strange slow-responses are still there. If I only knew how to find the cause of this.
