Unexplained Slowdown
by Ian Thomas 18 Jan '01

18 Jan '01

When I upgraded to Zope 2.2.5 access to my Zope over the web slowed down dramatically and I haven't been able to figure out why. I am interested in ideas I can try to track it down the problem or at least quantify/benchmark the slowness. 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. Thomas

Variable sort and multiple sort in dtml-in
by Loren Stafford 18 Jan '01

18 Jan '01

On 02 July 2000, Adam Karpierz, posted a patch that would allow an expression for the sort specification for the dtml-in tag. Did that patch, or something like it, ever find its way into the Zope core? I also seem to remember some discussion of sorting on multiple items (but can't find any trace of it in the archives). For example, in an employee directory, sort on employee name within department. Anyone know how? I'm trying to provide user-specified sorting on the records I pull from a SQL database. When the user specifies sorting on Department, I assume he wants the records order by Name within each department, but I can't see how to do that with ZSQL or dtml-in. -- Loren

Re: [Zope] case insensitive searches

Oracle, e.g., provides functions "LOWER" and "UPPER" that you can use in SQL expressions. They can be used to implement case-insensitive searches. Look at the list of built-in functions for your database. Dieter

High Performance Zope
by Vincent Stoessel 18 Jan '01

Hello All, How does Zope respond under heavy load? can Zserver handle serving out 200-300 zope pages per day on a busy website? Would it be better to use pcgi to plug it into apache? Thanks in advance. -- Vincent Stoessel vince(a)idev.com Internet Applications Engineer IDEV http://www.idev.com V: 301 495 7345 x129

i had the intermittent "browser displays the CSS text and not the real page" in another situation go away by expressly setting the content type in the linked CSS file. the first line would become... <dtml-call "RESPONSE.setHeader('Content-Type','text/css')"> jens on 1/17/01 8:20, Martijn Pieters at mj(a)digicool.com wrote: > On Wed, Jan 17, 2001 at 10:07:30AM +0000, Chris Withers wrote: >> - When you resize the top frame, you get back a load of CSS (but as text >> and without a content type) This didn't happen in a2. > > If you switch to inline CSS (instead of linked CSS) this problem will go > away.
