Dear Friends,
Please take a look at this performance monitoring shots.
This server is so slow. Is something wrong with the hard
drive or the memory? What settings can I do to fix the
problem?
Thank you
Debby

Hard drive :

F' drive total hd space = 819G space
available = 431 G
CPU = 2.80 GHz
RAM = 2.09G
Operating System = Windows 2000 SP4
What is the underlying physical disk structure?
What is the average disk queue length?
Does sp_who2 show many blocked processes?
FYI, a properly tuned SQL server should almost never page fault, however
some file write operations, mostly backups or file copying, can show up as
page faults to perfmon.

The disk structure is like this:
Hard drive :[vbcol=seagreen]
sp_who2 active show no blocking processes
Thanks

Also, do you have any other applications running on this box?

|||Take a look at the execution plans of your problem queries. The i/o metrics
indicate sequential scans so perhaps some index tuning is needed.
Hope this helps.

|||Debby,
Looks like you have plenty of capacity there and should be experiencing good performance. The Cache Hit Ratio for SQL is high, but that does not mean that all is well. I would suggest looking at other areas like the number of index searches per second,
full scans per second, readaheads per second and page splits per second. This will give you a quick indication of issues.
If Readaheads/sec is high (over 100), then you probably are missing an index somewhere or have a sequential process that should not run during the day. High Index scans and full scans also may indicate index issues, but you must also look at the transact
ions per second to get a good feel. Low transactions and high Index searches is not good for individual response time or scalability, while high transactions and high Index searches might be expected.
