I think you are missing the point here, gentlemen - the problem was not to impress potential clients or what kind of hardware to use, but to find a way to optimise the queries and the speed of DB-accesses.
This does not change the fact that there are some problems or issues with DB intensive Zope apps. Basically what Andreas and Maik are saying is that Zope sucks^H^H^H is sub-optimal when building DB intesive apps unless it is on the top-of-the line hardwara - which is kind of sad, because only last summer a 450 Mhz machine with Linux was pretty decent, and something that competing products would have no problem performing pretty well on.
hi, what I tried to say was: if you use a clever system of caching you can ran heavy load with moderate hardware. In my opinion clever caching is the key to build highly dynamic internet-applications which will give you although an impression of speed. Using the right combination of Accelerated Cache Managers, RAM-Caches and reverse Proxies will give you performance. Optimizing your DTML, your DatabaseQueries and so is necessary, but thats peanuts in comparison. Most people want ZOPE serving many users with many DB-queries without caching at all and complain about ZOPE's performance... that's unfair, I would guess...;-) greetings, maik.
