Improve this question

i used this example for performance test

someone says that netty's performance is so fast. It can process 1,00,000+ concurrent request/sec (check the below links)

http://www.jboss.org/netty/performance/20090303-mheath.html

http://www.jboss.org/netty/performance/20090607-asalihefendic.html

but when i try with this example it's give me only 107 req/sec with 1000 concurrent request

ab -n 10000 -c 1000 http://localhost:8080/

Server Software:
Server Hostname:        localhost

Server Port:            8080

Document Path:          /

Document Length:        230 bytes

Concurrency Level:      1000

Time taken for tests:   92.784 seconds

Complete requests:      10000

Failed requests:        0
Write errors:           0

Total transferred:      2900000 bytes

HTML transferred:       2300000 bytes

Requests per second:    107.78 [#/sec] (mean)

Time per request:       9278.431 [ms] (mean)

Time per request:       9.278 [ms] (mean, across all concurrent requests)

Transfer rate:          30.52 [Kbytes/sec] received

give me suggestion where is the problem

Can someone one please share any web example or reference highlighting performance benchmark of netty.

You have zero dropped requests and I would benchmark using Siege and compare with other similar setup. Also what kind of system are you using? Probably you also need to increase file descriptor for this to work. Also you need to configure JVM before doing benchmark. Something along these lines:

-server -Xms2048m -Xmx2048m -XX:+UseParallelGC -XX:+AggressiveOpts -XX:+UseFastAccessorMethods
