nginx - Analyze django performance

Question

I installed virutalbox on my mac, then installed centos5.9 in it to run django, and tested it with http_load. I don’t know how the performance of my program is. Please analyze whether it is normal

Mac OSX: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz | Frequency: 2359.617

Virtual machine: virtualbox centos 5.9, single core 1G memory

Environment: nginx uwsgi django1.5

Use http_load to test the homepage. The homepage is considered a dynamic page:

$http_load -p 20 -f 100 urllist.txt 
100 fetches, 20 max parallel, 471417 bytes, in 0.763381 seconds
4714.17 mean bytes/connection
130.996 fetches/sec, 617538 bytes/sec
msecs/connect: 8.16768 mean, 99.94 max, 0.082 min
msecs/first-response: 131.252 mean, 225.497 max, 0.055 min
93 bad byte counts
HTTP response codes:
  code 200 -- 93

Check the nginx access log and sometimes there will be a 499 error

Answer 1

499 error code is client has closed connection This means that the client connection has been closed. It may be caused by the server processing time being too long
