We are running Apache HTTP Server on a Windows XP machine with 2.79GHZ and 1 GB RAM , Weblogic 9.2 is running on another machine with the same configuration as Apache HTTP Server machine and on a third machine which is a 2 CPU,2.79 GHZ and 4 GB RAM machine we have Oracle 10g running We are doing a load test with 20 concurrent users .We see the access.log and apache is processing g around 140 HTTP Requests ( GET + Post) through and forwarding to the Application Server . We see that Apache is peaking to 100% where as the Application Server and the DB Server remain underutilzed . The Application is using JDK 1.5 and Spring Framework is being used . The Application does to have complex business logic and POJO classess are being used in all the layer Presentation Layer,Business Logic Layer and the DAO Layer. The Thread Count We see for Apache is 254 Why Apache peaks upto 100% ? 1. Is it becuase 140 requests per second it processing is too high 2. Some Configuration settings need to be changed ?
