Hai, First thanks for your tips. The main problem was, I think the short memory. If ZOPE swaps to much, when its active, the performance goes deep down. I use alkaline search, for the sitesearch.In default it starts some threads- too heavy requests for this machine. The server was near stopping; only swapping. Playing around with cache-parameters and 2 serverthreads didnt help. Now the server solves the "alkaline test" and stays by an acceptabe processsize. In addition to the memory upgrade I changed some details in the LocalFS, what saved some MB's too. Torsten.

Is there a way to disable caching for products/attributes/objects ? I think this would be nice for some sites which have not too much requests but a large amount of data.
