Actually the RAM usage is less on WC2, because you're not forced to have all 27 fields in a database. There is some overhead involved for every field added to a database, so if you keep it down to the minimum necessary fields you will save a lot of RAM.Here's the RAM equation for a single database: (size of db file on disk) + (#records * #fields * 4)Having 2 separate db files open is no different than having 1 db file containing both databases. Except it's faster to search just the 1 database you're interested in.>I have also noticed some comment on the Webstar list about WC loading >another copy of the databases when a Webstar SSL transaction is invoked. This only applies to plugins. If you run WC2 as a CGI it's not an issue. And we're working on a plan to get plugins working the same way (probably not until the following release though).Grant Hulbert, V.P.
