Hi all, I am wondering if, having say 15 zope sites, with an average zexp size of 70Mb (but two of 200+Mb), it is better to have multiple instances or not in order to reduce overall memory consumption. I know memory is cheap, but I really can't upgrade my server, I have 1.5Gb of ram and I had to tweak zope.conf to reduce cache-size and pool-size. My server is still using swap, I have now 3 zope instances (mainly because of products versions conflicts) and I don't know if using 2 or only one instance would be better memory wise. Thanks in advance, Lorenzo
