I have a report page that when going through the maximum amount of data takes maybe 5 seconds to generate on both my Linux server and on the Windows machine I use for development. This report page is a Page Template generated from external product code. There is no external database involved - just Zope objects. I was getting weird periods of serious slowdown on my server, and traced the problem to multiple users running this report at the same time. On the windows machine, if I generate 4 requests, the time to return all of them is approximately 20 seconds or x*N response time. On the Linux machine, however, I seem to be seeing MUCH longer response times for simultaneous requests for the same data. Could this be an issue with the way in which I have Zope configured on the server? or does the Linux version do something differently? I have seen hints of "read only" transactions, but have not been able to figure out how to code these. Is there something I could do to make these read requests for the same data not interfere with each other? --Sean
