We have developed a vacation rental application in ASP.NET with SQL server as DB. Used .NET 3.5 with Entity Framework. Currently QA test this with P4 machine with 2GB RAM. Looks like the processor utilization goes up to 50% for every request. All our DB retrieval timings are < 1 sec. The page load is very slow. We applied all performance tips at IIS level (Compression, Keep Connection Live) and caching to limit the bandwidth (which is normal at 300-500 KB).
We use Telerik RAD Controls for most of the pages. It has been decided that the server hardware is the bottleneck (from HTTP Analyzer measuring the Wait time).
We expect 100 concurrent users 100-200 transactions per second. We run both the IIS & SQL server in the same server at well & hosted in asphostportal.com
The legacy application responds very well at the same server - No EF, Telerik Controls etc.
Can anyone recommend good hardware configuration RAM, CPU Speed etc & what other techniques to speed up the performance?
