You alerady have it: InMsgs gives a number of messages received by amavisd, and its hourly mail rate. To measure a peak througput with a given number of child processes, pause a MTA queue for a while so that some mail accumulates in the queue, then restart amavisd, flush the queue, and by the time a queue dries out see what the InMsgs mail rate is. > or the average size of a message, etc.; You already have it: InMsgsSize 2151MB 130MB/h 100.0 % (InMsgsSize) InMsgsSizeInbound 1370MB 83MB/h 63.7 % (InMsgsSize) InMsgsSizeInternal 303MB 18MB/h 14.1 % (InMsgsSize) InMsgsSizeOutbound 568MB 34MB/h 26.4 % (InMsgsSize) > I see for instance the opposite, e.g. TimeElapsedTotal, which sound the > number of total time taken to process all the incoming messages > since the start of the amavisd daemon.

This arithmetic would only be valid if you only used one amavisd child process. As usually there are dozens, especially on a multiprocessor host, parallelism must be taken into account, so mail rate would be about TimeElapsedTotal / $max_servers during times when all child processes are busy. > This sound an unbearable low value, as I achieve it in > more or less a Dual-Quad Core Xeon 64bit with 12GB of memory, > as well as a single core virtualized Athlon32 with > 384MB of memory. Are those reported values reliable? The figures are reliable. But keep in mind what is being measured.
