dear sir,
we r wrking on a project which requires output with high performance & speed (i.e we want an our system to perform 2000 queries in 30ms , for which we are using WINDOWS SERVER-2003 & XENON Dual processor(3.8 GHz) with 1Gb RAM and with latest configuration) ,but we are facing a very strange problem .
when we perform load test on SINGLE xenon processor , we get output in 900 ms ,but when we use Dual processor , we get out put in more time ,but in actual cae it should happened be reverse ,(i.e. it should take less time since we r using Dual processor), so can u plz tell me ,what could be the possible cause of this problem ,is there any need to do some performance tuning in WINDOWS SERVER 2003 ? if so then what??? plz reply me with Cc at :: <<email deleted by mod>> :::
