I have tried to find information on how many Zope instances can be run on a single machine but all searches have failed to be definitive. Is there any information on this, because I would like to have a separate instance for each of my customers running on a different port number and it would be useful to be able to predict the number of servers I would need. Regards Garry

As you might imagine: everything depends on the resources: Ram, diskspace, CPU. A Zope instance might take as little as 80MB Ram or up to 2GB per process. A site might consume no CPU, a Zope-based p0rn site might require several machines...so basically we can not give a valid answers..everything depends on a lot of parameters and there is no Zope formula.

Andreas OK, so does the amount of RAM needed depend mainly on the size of the data.fs or is there another major component? regards Garry

You should have >2G data.fs and your zope instance could consume about 30MB. It depends on cached data amount. Regards, JL.

As said: there is no formula. Memory consumption depends on caches, third-party products, products with memory leaks.......nothing more to add. Andreas

This is only one component: A process with an open "FileStorage" needs 8 bytes per object in this storage. Other RAM requirements do not directly depend on the storage size. -- Dieter
