Hi, We've been experimenting with ZEO for a few months. The intended use is to have a ZEO client on our LAN, one on the Internet backbone in China, and one in the US, but there are two problems preventing us from using it: 1. updates are very slow, slower than accessing the ZEO client closest to the ZEO server directly 2. logging in updates the database, so they are consequently also very slow (in addition: to use it well we need a distributed director, and atomically updating a set of ZEO installations is not trivial.) Why does logins update the database? Is there any way to turn that off easily? We tested running the ZEO server on our LAN, and the ZEO client on the backbone of the Internet, communicating over a 64kbps DDN line... It took several minutes to log in! :) Most people thought our server had crashed. Would it be possible to support asynchronous updates (optimistic locking) and conflict resolution in the future, allowing for no wait time? (sort-of like Notes and CVS) Bye, -- Bjorn <bjorn@exoweb.net>
