The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Advise for Tuning MS SQL 2000/2005 server or Specing a new server.

Asked by n3mtr in MS SQL Server, Computer Servers

Tags: 2000, sql, disk, new, tuning

We are having performance issues on our current sql server, we are thinking about a new server.  Our current server peaks at about 300 batches per second.  Above that the users start to complain about performance.  The specs on the current server:
HP ML370G3
2-3.06Ghz Xeon Processors(Prestonia)
4 gigs of ram
5-72 gig 15K drives in 1 raid 5 array
(I know it is not optimal to have everything on one array, but I didn't set this server up)
Server 2003 Standard
SQL 2000 Standard(I know it can only using 2 gigs of ram)
Currently the Main Database is around 25 gigs.

Performance info:
SQL Cache ratio 99.3%
connections 125
%disk usage 60%
Disk Queue length avg 1.3
Proccessor Queue avg 6
% processor 65%
requests per second 275 average, people start complaining over 300.

Would chainging the drive configuration make a big difference(going to multiple raid 1's or 1 raid 1, 1 raid 5)?
Would going to Server Enterprise/SQL enterprise and adding memory make a big difference(expensive)?
Would going to SQL 2005 make a big difference(would have to test the application first)?

Here is the server I've speced out:
DL380G5
2-Quad-Core 2.66Ghz Processors
8 gigs ram (4x2g)
P400/512 controller
2-72G 10K drives for Boot(raid)
4-146G 10K drives(2 raid 1 arrays, one for databases, one for logs)
Windows 2003 X64 Standard
SQL 2005 Standard or Enterprise(Not sure yet)(may have to use SQL 2000 temporarily)

Does this make sense?  Would you tweak the specs any?
I've never used 2.5" drives in a server, but that is all you can get these days.

This is a web based appliation written in ASP.  It uses a lot of stored procedures.  It seems to slow to a crawl when people are running a lot of reports or running through certain weekly processes.  I new performance optimized asp.net version is in the works, but it is at least 6 months out.  They don't want to take any developers off to optimize the old code.
