Moving a database from one machine to another and the lack of speed

Dear All,

We have a procedure that takes12 minutes to run on the first server but
that same procedure now takes 3 hours to run on the second server using the
same data. Does anyone have any suggestions why this is happening and how
to make the procedure faster on the second server

Thanks in advance.

No idea - the usual advice if you see something like that is to a) update
statistics, and b) use Profiler to identify what's taking so much time. You
can also capture the execution plan in Profiler (or use Query Analyzer,
which is a bit more user-friendly), and compare it against the plan on the
original server.

If that doesn't help, you'll need to give more details about your
environment - are they the same MSSQL version? The same hardware? Do you
have the same database schema (including indexes etc.)? Are the database
files exactly the same size? Are they using the same recovery model? Is the
data the same (or nearly so)? Is everything slow, or only certain
procedures? Etc.

Move Temp DB and Logs to get more speed?

We are running a server with IIS and SQL 2K using the following
configuration:
C: OS/Inetpub
D: SQL 2K DB/Logs
E: IIS Logs
F: Not Used
G: Not Used
We have a single SQL 2K DB that all the websites use.
I'm currently constrained to a single server and the drive configuration. I
would like to optimize better by using the new F: and G: drives.
Additionally the C: and D: have no problem keeping up so I could move IIS
logs to the C: drive if needed.
Based on reading I've been doing it sounds like I will get the best
performance from moving the TempDB and the Logs files to different drives
but which configuration would be best:
F: TempDB DB and Logs
G: Our main DB Log Files
or
F: TempDB Logs
G: Our main DB Log Files
or
Something else.
Please suggest my best route.
Thanks!
It's a best practice to have the data and logs on separate partitions. This
is both for safety (High Availability) as well as performance. Also, try to
keep tempdb separate from your app DB's. Thus, you could go with:
D: app data
F: app log
G: tempdb
Try that first. You can also move the tempdb log to F: and see if that
improves or degrades performance. Logs should not be placed on RAID5
partitions.

can leave it. If you still have perf issues, then move the log to another
