asp.net - SqlServer Express slow performance -

-

i stress testing .net web application. did 2 reasons: wanted see performance under real world conditions , make sure hadn't missed problems during testing. had 30 concurrent users in application using during normal course of jobs. users had multiple windows of application open.

  • 10 users: not bad
  • 20 users: slowing down
  • 30 users: very, slow no timeouts

it loaded on production server. virtual server 2.66g hz xeon processor , 2 gb of ram. using win2k3 sp2. have .net 1.1 , 2.0 loaded , using sqlexpress sp1.

we rechecked indexes on of tables afterword , should be.

how can improve our application's performance?

this thought of, check see how memory sql server using when have 20+ users - 1 of limitations of express version is limited 1gb of ram. might simple matter of there not being enough memory available to server due limitations of express.
