[Asterisk-Users] show translation

[Anton Krall]

Im reading some tips on dimentioning asterisk servers and I was wondering
about the show translation command. 

The numbers shown, what do they mean? Ms needed for transcoing but... How to
measure if they are good or bad?

For example:

        g723   gsm  ulaw  alaw  g726 adpcm  slin lpc10  g729 speex  ilbc
   g723     -     -     -     -     -     -     -     -     -     -     -
    gsm     -     -     2     2     4     2     1     9     -     -    24
   ulaw     -     5     -     1     4     2     1     9     -     -    24
   alaw     -     5     1     -     4     2     1     9     -     -    24
   g726     -     6     3     3     -     3     2    10     -     -    25
  adpcm     -     5     2     2     4     -     1     9     -     -    24
   slin     -     4     1     1     3     1     -     8     -     -    23
  lpc10     -     7     4     4     6     4     3     -     -     -    26
   g729     -     -     -     -     -     -     -     -     -     -     -
  speex     -     -     -     -     -     -     -     -     -     -     -
   ilbc     -     8     5     5     7     5     4    12     -     -     -

My setup is this, I have 2 sip atas using ulaw from phone to asterisk, then
from asterisk to another asterisk I use ilbc and then from asterisk to phone
again, ulaw.

Can you help me understand the numbers?
