If it is Superserver - more or less similar. If critical resourse
is CPU - Classic is much better on CPU sharing, though loses in
single-user and low loaded multi-users modes. There is one more issue
- if you use local connection string like 'C:\mydatabase' -
serialisation of queries is made in client library, if TCP/IP, like
'localhost:C:\mydatabase' - in Supersrever internal threads only.
