Hi,

I am new in SQL SERVER.

Could you please tell me the difference between SQL SERVER 2008 R2 (RTM) and SQL SERVER2008R2(SP2).
And which one is best for production database.

Thanks

RTM = Ready To Manufacture, SP2 = Service Pack 2

The one with SP2 has service packs 1 & 2 already in the installation bits so that you don't have to upgrade your system after installing the RTM (the original relase). Go with the SP2 one.

How do you determine normal? Have you measured values to compare? Are you checking specific queries that are slow? Have to examined execution plans? Are they "normal" to something you compare them to? Is the client measuring from their application? Perhaps something else on another server or the client is running?

There's lots to check and as Gail mentioned, it's not likely this is version related.

Performance is most often related to the code or the structure. But, sometimes it can be other things. For example, do you have any process for maintaining statistics on your servers? If not, you might want to, at a minimum, run sp_updatestats to get the statistics updated. But performance tuning is a giant topic. You need to gather metrics, compare them, comprehend their meaning and then begin to address the issues they suggest. If you're just getting started in SQL Server, you're better off focusing on the basics like ensuring that you have good backups in place on your databases, things like that.
