Hi , Can you please tell me about your requirements like for example how many processes do you want to create for handling the request, it seems to me the number of processes are very high, you can try out increasing the number of threads per process that way you can reduce the number of processes, also introduce ThreadLimit param in order to increase the ThreadsPerChild.Let me know if I can help you. Thanks -A
