I have a few complex methods (DTML skins ) which execution causes Zope to become slow. As a result it can take from 4 to 10 seconds to respond a single request to any of those methods, on a Win2K Pentium200 test box plenty of RAM, and that's bad for an application meant to support up to 20 requests at the same time, whatever the destination hardware could be. (Caching wouldn't help because they are methods related to personalization stuff) Facing the step of translating those methods into Python Scripts, I'm considering the use of External Methods instead. Are they faster than Scripts? Has anyone made performance comparisons between the different existing types of scripts, in order to optimize Zope's performance? Thanks in advance, Ausum
