hi, anyone know how to maintain the performance of database while mirroring. Because we notice that the system become slower after we do the mirroring and back to normal while we pause the mirroring. Please advise on what can I do to get a better performance while mirroring.

Thanks in advance!

I would double check:
1- network bandwith and consumption ( drastically enhanced with SQL2008 ! in case you still need an upgrade reason )
2- I/O subsystem performance
3- ram pressure

of course ... before and after mirroring activation.

Can you post these properties of your two sqlserver instances ?
Select  Serverproperty('Edition') as Edition
, Serverproperty('ProductVersion') as ProductVersion
, Serverproperty('ProductLevel') as ProductLevel

You posted in a SQL 2005 forum !

Your server is SQL2008R2 !

btw the current service pack for SQL2008R2 is SP2 !

Upgrade to SP2 if you can and then reassess your issue
