The present invention relates to performance optimizing method for application server. After receiving the network service request, the network engine creates corresponding task associated with the service target before handing over the task to the task despatcher. If the number m of the work threads in current thread pool is smaller than the upper limit T_M of the thread pool, the despatcher will create one new thread in the pool for processing the task.
