有个 Florian 的人简单测试了一下 Jabber 服务器软件的情况，他通过给他 jabber.ccc.de 服务器 log 上有 s2s 的服务器记录作为目标，向这些主机发送 jabber:iq:version 查询，在他的 log 上一共有 542 个主机，得出的结果如下：

 jabberd1 => 168
 ejabberd => 109
 jabberd2 => 78
 unknown => 64
 Wildfire => 49
 jsm => 20 (I guess this is pre-1.4.3 jabberd1)
 MSN Transport => 13
 ICQ Transport => 12
 AIM Transport => 5
 Yahoo! Transport => 5
 JIT => 4
 MU-Conference => 2
 Jive Messenger => 2
 XMPPPY Yahoo! Transport (Dev) => 2
 dotJ => 1
 XCP => 1
 SMS - Transport => 1
 ejabberd mod_proxy65 (unofficial) => 1
 RSS component => 1
 Jobble transport => 1
 psyced => 1
 Gadu-Gadu Transport => 1

结果是 jabberd 1.4.3 最受欢迎获得 115 个返回结果,
ejabberd 1.1.1 47个 + ejabberd 1.1.0  40个.

操作系统使用最多的是 Linux 2.6, 171 replies, 然后是 Linux/unknown and Linux 2.4.

Most "outdated" versions were ejabberd 0.7.5 and jsm 1.1.3.

Using just the public jabber-servers reveals pretty much the same, the
single interesting difference is that Wildfire is only used twice
within 117 servers.
