Comment (by T_X):

 For test 2 I'm having the following results at the moment.

 Current trunk ([5150]):
 {{{
 792.81
 3.90
 3.89
 3.88
 3.77
 3.81
 3.79
 3.80
 3.83
 3.80
 }}}

 1.8.2:
 {{{
 794.95
 4.03
 4.10
 4.05
 4.06
 4.05
 3.97
 4.03
 4.03
 4.01
 }}}

 So the very long delay in the beginning seems to be present in both
 versions. The common latency seems to be slightly lower though.

 But looks interesting, that it usually seems to be in the range of 790 and
 795 seconds, as if some specific thing needed to time out first.
