如果我不知道message type for the message in the message queue, can I
still read that message out of the message queue?
第二个问题, 我想知道message queue 里面都放了些什么message without
reading messages literally out of message queue? Is there any shell script
command to do that ?

我想知道主要怎样系统地 measure 一个 message server, 比如有哪些主要测试工具 (
jmeter, tsung 等等，他们的优劣), 主要需要测试好哪些 measurements (e.g.
messages/sec, connections/sec, kbits/sec ...)
message 可以是自定义的。 e.g. JSON over TCP, 甚至 UDP
也可以是 HTTP messages。其实一直没有定量研究和测试过 HTTP 跟 自定义的 简单
message 包比较起来，到底有多 heavy, 延迟高多少，处理能力要额外耗费多少。

端内网的，也便于从公网上收发 messages. 比如就当 HTTP server 或者 gaming

发帖数: 550 | 4 其实严肃讨论的，我的12306架构又转移到出票机（支付系统）上面来了。
如果要达到我说的性能，其实支付端要实现一个ACID的系统。幸好我们的应用简单，不
需要通用ACID数据库，只需要简化成一个ACID message queue就好了。
ACID message queue，输入是有序的message。每个message带一个单调递增的message
ID。甚至增量严格定义为1没有问题。
如果抢票机死掉，这个message queue负责回放某个message ID开始的所有交易。恢复
现场。
其实这个message queue关键技术在于存储。存储设备的IOPS要达到至少1M IOPS。
网上搜搜，就可以看到多少battery backed RAMDisk或者SSD能够达标就好了。

1. 文件系统开销呢？
答：raw memory map file，可以确保每次写一个record（512 byte以内）正好一个IO

2. message和action要绑定在一起，或者说Atomic，否则出来的message次序和action
