Hi, I'm a beginner on this field. I want just to do some simulation about multiprocessor programming. What I'm trying to do is to test performance of nginx by using Apache Benchmark. So, I added "server.max-worker = 8" to default "nginx.conf" and ran Apache Bench through a command, "ab -n 100000 -c 1000 xxx.xxx.xx.xx". However, server computer's max CPU utilization showed 30% as if it had just 2 cores. Without "max-worker=8", max CPU utilization is 15%, so it is sure that there was some change. How can I increase the CPU utilization to 100%, which is 8 core?? Followings are running environment, O/S: Ubuntu 12.04 (in VIrtualbox4.2) CPU: Intel, i7-3610QM (which has physical 4 cores, but virtually 8 cores considering hyperthreading) RAM: 4096MB nginx: 1.4.1 Apache: 2.2 notes-I checked that CPU utilization can be 100% with another application. If anyone has idea on this or needs more information about my setting, please let me know. Thanks in advance. -- With regards, Jason Koh (고범규) -- With regards, Jason Koh (고범규)
