Most likely, it's locking issues. How long does your synchronization take to finish?

Database optimization would include performance tuning, and also things like backup schemes (backup size), data-scalability and normalization, storage planning (disk use), etc.

Are you asking about a way to programmatically determine that, or to determine it after it's already done and over with and the code is no longer running?

By default, it will use all of them. You can change that by setting CPU affinity, so yes, you could use 2 out of 43 (that's quite a server!),...

In that particular case, it might use the index, but if so it will probably be an index scan instead of an index seek.
Would StartDate be selective enough...

It sounds like it might work to centralize the database, like you're talking about. How they query the data and how much data will be transmitted at a time...

I just ran this test:
set statistics time on
go
declare @A char(1)
select @A = left(col4, 1)
from dbo.sometable
select @A = substring(col4, 1, 1)
from dbo.sometable
go 100
Execution time was identical for both commands.

The order of columns in the index matters, because of the...
