Hi, I have a django site running with nginx 0.9.4 + uwsgi the latest stable (from pip install). My uwsgi starting opts: -s /tmp/storefront.socket -M -p 16 -d logfile.log -L -i --pythonpath /pathtoproject --module wsgi -t 120 -l 2048. The problem is during the rush hour, 2 cpus are working fully loaded. Here is a screenshot of top:

Traffic is sometimes heavy but CPU never reach like above, load average never reach 2.5-3.0. System is 32bit debian lenny, and cpu info: vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU 3065 @ 2.33GHz stepping : 11 cpu MHz : 2333.548 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes Someone says maybe because of too many uwsgi worker processes. I have tried start with 4, but if that site is laggy even in non rush hour and log is full of queue is full warning. I paste also my nginx conf: http://dpaste.com/hold/648415/ Any help appreciated. -- KR, Xi
