OK, yet another thread is closing, where I am the only poster :). For the
record, I find out that starting asterisk with -p option (realtime) gives
the following table, which now makes more sense. But what is surprising for
me is that the load of the server was close to 0 in my original post, thus I
would expect similar results. So I'll assume that the previous translation
table (without -p) does not show the real capabilities of this server.
Lesson learned: start asterisk with -p for close-to-actual translation
values.
