Hi, We are new to Zope and are trying to create a form- and db-intensive web application using Zope 2.4.0 (though I'm testing in 2.5 also). I've noticed that our complex forms (which use nested dtml-in loops) are running extremely slow, taking more than 30 seconds on the server side (450MHz Pentium II w/ linux). So I created a snippet benchmark and noticed something peculiar, in that running a simple loop for the first time is often very slow, however in subsequent refreshes of the document the loop runs almost 8-10 times faster. I turned off caching as much as I know how (in the browser and zope). Here is the benchmark I'm using: <dtml-var standard_html_header> <dtml-comment>Note: My standard header turns off browser caching.</dtml-comment> <dtml-call "REQUEST.set('starttime',_.DateTime().millis())"> Start Time (ms): <dtml-var starttime><br> <dtml-call "REQUEST.set('testlist',['1','2','3','4','5','6','7','8','9','10'])"> <dtml-in "testlist"> <dtml-var sequence-item> </dtml-in> <br> <dtml-call "REQUEST.set('endtime',_.DateTime().millis())"> End Time (ms): <dtml-var endtime><br> <hr size=1> Delay (ms) = <dtml-var "endtime - starttime"><br> <dtml-var standard_html_footer> Any help would be extremely welcome...as is, the site is too slow to demo to potential clients.
