ASP.NET托管应用程序的最佳硬件配置

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 have developed a vacation rental application
