Erlang-China

既然上一篇八卦谈到了Erlang在爱立信里面的地位（C++至高，B教主满塞），这里就介绍一个PPT
《Comparing C++ and Erlang for Motorola Telecoms Software》http://www.erlang.se/euc/06/proceedings/1600Nystrom.ppt ，有兴趣的下载看看
里面以一个纯C++，一个纯Erlang和一个C++ Erlang混杂的系统进行对比和测量，有丰富的图表

RQ4: Performance
*Time:
Max. throughput at 100% QoS:
Pure Erlang DM is twice as fast as C++ DM
Erlang/C is ½ as fast as C++ DM , but still exceeds throughput requirements
Roundtrip times
Pure Erlang DM is three times as fast as C++ DM
Erlang/C is between 26% and 50% slower as C++ DM
*Space:
Pure Erlang and Erlang/C both have 170% greater memory residency due to (fixed size) 5Mb runtime system
