sql server replication : row filter where clause (busy db performance hit?)

Hello.

I need to setup a filter for a really busy db
that we are replicating. I was wondering what
type of filter to use. I am afraid that the
where clause of a row filter will create a major
performance hit. I was looking into dts and
Transformable Subscriptions but am not real clear
if that would be better.

any advice would be appreciated.

thanks,

it's static. where fkstoreid in (5001,5002)

like that.

Would this be a static filter or a dynamic filter, ie where store_id=2
(static) or where store_id=hostname() (dynamic)?

There is more processing involved in using filters. The impact may vary
widely.

This filter probably is optimal.

You might want to look at replicating the execution of stored procedures -
this can lead to radical performance increases.
