I got 2 nearly equal servers, setup by "quick installation" from wiki.
And one "Mail Server VE".
Old server: CentOS 5.3 x86_64 2.6.18-128.2.1.el5.028stab064.7
New server: CentOS 5.5 x86_64 2.6.18-194.8.1.el5.028stab070.2
So the same VE process 500 Mails per minute on Old server
And 50 Mails per minute on New server.
Once again: servers are almost equal!
Test done like "TEST, MIGRATION, TEST, MIGRATION, TEST"
right now i`m done testing HNs with bonnie++:
old HN:
Version 1.03 ------Sequential Output------ --Sequential Input- --Random-
-Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks--
Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP
8G 33482 58 35455 12 16781 3 37141 56 40122 3 86.8 0
new HN
Version 1.03 ------Sequential Output------ --Sequential Input- --Random-
-Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks--
Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP
8G 33136 46 36209 8 19819 4 49741 61 66728 5 185.2 0

The main test done by "postal smtp server benchmark" which is running on another server:
[root@longbeach postal-0.70]# ./postal -a -t 10 -M 10 -m 100 my-mail-ve.org user-list-filename
time,messages,data(K),errors,connections
10:53,285,16337,0,295
10:54,392,20716,0,392
10:55,385,21213,0,385
10:56,390,21503,0,390
10:57,393,22093,0,393
10:58,439,24806,0,439
10:59,435,23798,0,435
[root@longbeach postal-0.70]# ./postal -a -t 10 -M 10 -m 100 my-mail-ve.org user-list-filename
time,messages,data(K),errors,connections
11:21,71,4790,0,81
11:22,88,5016,0,88
11:23,80,4391,0,80
11:24,83,4300,0,83
11:25,81,4187,0,81
11:26,80,4499,0,80
11:27,82,4211,0,82
11:28,78,4152,0,78
11:29,82,4274,0,82
[root@longbeach postal-0.70]#
So, first is "old HE" and second is "new HN".
"new HN" is faster than "old HN" but VE works 5 time slower!
