Echo servers in some languages

いろんな言語＋フレームワークで echo server を書いてみました。

いくつかのコードはサンプルプログラムにあったそのままのコードを書いていて、 epoll, thread 版は自分で作成したものです。

各 echo server の実装は全く同じものではないのであくまでも参考ですが、パフォーマンスはこんなかんじです。

test environment

client and server are connected by Gigabit Ethernet.

client (sag14)

Debian 5.0.4 (i386) Linux sag14 2.6.26.5 #2 SMP Mon Sep 29 14:17:40 JST 2008 i686 GNU/Linux Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz (dual)

server (sag15)

Debian 6.0.2 (amd64) Linux sag15 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 x86_64 GNU/Linux Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz (dual)

test command

bench.sh does kick client 3 times with following option.

./client -c50 -o2 -h10000 sag15

C++ epoll

server:

./server_epoll

result:

Throughput: 117036.86 [#/sec]
Throughput: 118702.63 [#/sec]
Throughput: 119129.38 [#/sec]

with forking.

server:

./server_epoll -f2

result:

Throughput: 146602.29 [#/sec]
Throughput: 132542.38 [#/sec]
Throughput: 149737.19 [#/sec]

C++ thread

server:

./server_thread -c120

result:

Throughput: 122903.04 [#/sec]
Throughput: 121306.08 [#/sec]
Throughput: 122511.62 [#/sec]

C++ libev

server:

./server_libev

result:

$ sh bench.sh 
Throughput: 96757.33 [#/sec]
Throughput: 132618.52 [#/sec]
Throughput: 132365.60 [#/sec]
$ sh bench.sh 
Throughput: 134189.84 [#/sec]
Throughput: 133924.71 [#/sec]
Throughput: 133706.54 [#/sec]

libev have dynamic event queue size. So, first benchmark is slower than after.

Haskell

GHC 7.0.3

server:

./server_haskell

result:

Throughput: 80391.53 [#/sec]

Throughput: 76325.74 [#/sec]

Eshell V5.8  (abort with ^G)
1> c(server_erlang, [native, {hipe, ['O3']}]).
