Hi, I'm running a Zope web application that obtains most of its data from a PostgreSQL 8.1 database in a virtual machine. I'm able to adjust the memory of this machine according to reasonable values and can choose between one or two (emulated) processors. The question is: How can I find an optimal relation between the virtual hardware parameters and PostgreSQL performance. I guess it makes no sense to blindly increase virtual memory without adjusting PostgreSQL configuration. Are there any experiences about reasonable performance increasing strategies? Are there any special things to regard in a VM? Kind regards Andreas. -- http://fam-tille.de
