Generally, AdminStudio operates under the standard one process - one thread model. AdminStudio tries to perform most of the database work on the database server. However, this leaves the OS with limited oportunities to balance the laod across multiple processors.
There are some execpetions to this architecture. The ConflictSolver OS Snapshot import is done asynchronously in a separate thread, which should give the OS the opportunity to balance the system load.
Over time, we will certainly make more functionality asynchronous and this should allow AdminStudio to perform better on these multiple processor systems.
