Hi all, One of my Zope sites is used by classes of students - up to 60 or so at a time. When they use the site the response time is really slow - they could be waiting minutes between clicks. The site uses ZSQL methods *extensively* and external methods. I realise that part of this problem is because of our Sun iron (2400 pystones - my *iMac* does 4400, and a PIII 500MHz does 5500), but as I can't get this site onto another box in the near future, I'm after other ideas. Can anyone give me some pointers (even just rule of thumb) to improve the response time? I was going to set the threads to be something like 32, but I've read other posts suggesting that wouldn't help too much. Is there someway I can profile what's going on for example? Any thought gratefully received. tone
