Hi Krishna
,
Slow performance get what what you get when trying to run a database on a personal computer.

Windows "servers" are just glorified PC's.
The PC I'm on now has 8 gig RAM and super fast disks (for a PC) and costs under $1,000.
Buying nre server (Uning Linux aill make everuthong faster (unless you have a netwotk latcncy oisdsie (check iostat)

>> RAID 5
RAID 5 causes MASSIVE updTE/DELETE INSEET DELAYS!
There are two types of I/O. and you are looking for "db file sequential reads":
Read this carefullyhttp://www.dba-oracle.com/art_disk_iostat.htmMost PC's have disk times between 15-20 milli-seconds . . . .
If you want doagnostics scripts, see here:

>> We are using one software it is a test tool for verify the data base posting speed from server to client systems
That's not a simple program, becsuse it is the sum of:
- database time (See here jhow to tune inserts (
- OS transfer time (SQL*Message from client)

>> In windows 2008 R2, database posting speed is very slow when compare to windows 2003 server .
Krishna, In sum,Windows is difficult to tune, buggy (weekly patches), and I would recommend and after you checl uyour nework speed, upgrade to a $20 K Linux server with SSD.
