The 4GB limitation is per database. I know of no limit of databases per instance, but each instance is limited to 1GB RAM and 1 physical CPU. However, SQL Express is multithreaded and will take advantage of multicore CPUs.
You are also limited to 16 instances per machine. Ara Avvali wrote: > The limitation with SQL express and 4 GB, is it: per machine, per > instance or per database?
