cause it can take all your cpu for some seconds. Here is what I had: <dtml-in Events > <tr> <td><dtml-var firma> <br>Tel: <dtml-var tel> </td> <dtml-call "REQUEST.set('temps',_.string.split(_vars['zeiten'],'/'))"> <dtml-call "REQUEST.set('siz',_.string.split(temps,'('))"> <dtml-if "_.len(siz) > 1" > <dtml-call "REQUEST.set('wt',_.string.split(siz[1][:-1],','))"> <dtml-call "REQUEST.set('siz',siz[0])"> <dtml-else> <dtml-call "REQUEST.set('wt',tage)"> <dtml-call "REQUEST.set('siz',siz)"> </dtml-if> <dtml-in tage> <dtml-call "REQUEST.set('tag',_vars['sequence-item'])"> <td valign="top" bgcolor="#e3e8ff" align="center" width="85"> <font face="ARIAL,HELVETICA" size="2" color="#3c5282"> <dtml-in zz> <dtml-call "REQUEST.set('st',_vars['sequence-item'][1])"> <dtml-comment> <dtml-var st> </dtml-comment> <dtml-if "tag in st"> <dtml-var "_['sequence-item'][0]"> <br> <dtml-else> <br> </dtml-if> </dtml-in > </font></td> </dtml-in> </tr> </dtml-in > that was basically it the outer <dtml-in> SQLmethod resulted in about 60 rows, the inner was done for every weekday i.e. 7 times. This resulted on an Ultrasparc in an executiontime of 10 CPU seconds, on a Sparc 20 it took more than a minute with a CPU load of nearly 100 %. I implemented the above in Class for the SQL-method, so the above was replaced by <dtml-var xyz> with xyz being a method of the class, which produced the same output as above. Besides being much more clear, cause it's pure Python, it takes now less than 0.5 CPU seconds on the Ultrasparc. Just wanted to share that experience :-) Mit freundlichen Grüßen Joachim Schmitz WWW-Consultant email: js@ac-copy.net tel: +49-241-89491-0 fax: +49-241-89491-29
