Performance Tweaks

I have a client that is having some performance issues with sql 2000
database. The application seems to move slow on the server as well as the
workstations so it does seem like a network or workstation issue. It seems
to be a sql issue. The server is a decent server with high P3 processor, 1
gig of memory, RAID 5 scsi drive array running 10k rpm. At this point they
are only "testing" this application, only a hand full of users are using
app. Any suggestions on performance tweaks would be great. They had a
puesdo-administrator that forced sql to use 500 megs of the 1 gig in the
server... other than that its all default.
thanks for the help,

MOve the log files to somewhere which is mirrored and on a different
physical drive than the data...Also the Data files for your database should
be on a different physical drive than master, model, tempdb.
This sets you up in a position where you can get up to the minute recovery
with no loss of data (using the backup with notruncate option.)

thanks for the help,
rob500 MB memory is not much for SQL Server, however, it all depends on how
big is your database and how many concurrent users, it may be enough, it
may be not. Open perfmon to check if there's any paging going on on the
server. Also, do you have correct index? How did you configure your data
files? Is your application using alot stored procedures? Are those
stored procedures very CPU intensive?
Without any detail, it's hard to determine what's going on.

you'll need to capture perfmon data and see where your bottlenecks are.
usual suspects.
RAM - 500mb is low and 1GB could be
CPU - Maybe you need additional CPUs
IO - RAID 5 with 10k Drives....that is rather slow. You may be Queueing up
IO requests
Indexes, bad sprocs, excessive blocking, deadlocks, etc
lots of work to do to figure this out
