There is a puppet cluster, composed by nginx,passenger,puppet. The number of
qps is 1000 currently,
and the processing speed of the whole cluster is pretty good,the average
processing time for the request is 0.25 seconds.
But it is a little slow from client report, a lot of processing time is tens
of seconds.such
as nginx log:
192.168.0.2 puppet - [07/Feb/2013:15:45:44 +0800] "PUT
/production/report/123.test.test.cn HTTP/1.1" 200 24 "-" "-" "-" 95.690
192.168.12.12:8140 200 *95.876*
The Normal request:
192.168.0.2 puppet - [07/Feb/2013:16:03:52 +0800] "GET
/production/file_metadata/files/123.py HTTP/1.1" 200 324 "-" "-" "-" 0.014
192.168.12.12:8140 200 0.105
puppet version:2.6.11
nginx version:1.0.9
passenger version:3.0.13 and 3.0.17
The Server cluster still have not reached the performance bottleneck
nginx proxy buffer is large enough
passenger conf :
passenger_root /usr/lib/ruby/gems/1.8/gems/passenger-3.0.17;
passenger_ruby /usr/bin/ruby;
passenger_max_pool_size 150;
passenger_use_global_queue on;
passenger_max_requests 4000;
passenger_pool_idle_time 100;
how to optimize?
