asterisk users - May 2004 - Asterisk resource consumption..

No this is not another of the "What hardware do I need?" posts.. :)

Just wondering if anyone has calculated the memory consumprion for 
running asterisk..

For example, when its idle it uses U MB or RAM,  uses V MB for each 
active Zap channel, W MB for each active SIP channel, X MB for each 
active IAX Channel and Y MB for each VM channel..

I often read posts where guys are throwing 1-2GB or RAM at a server and 
this seems extreme to me but there don't seem to be any numbers for 
people to use as a guide (could be placed on voip-info.org)..

Unfortunately my system is to small to do any real testing of this kind 
but I would be happy to help somone who has a bigger more active system 
to get the numbers..

Later..

Unfortunately, it is not as simple as just counting channel types.  You 
need to factor in which compression codecs are used, as each will have a 
different impact on the system.  Are multiple codecs used requiring 
transcoding, or just one?  And what is Asterisk being used for?   Is 
Asterisk monitoring the channels or is native bridging permitted?  Is 
muisc on hold used, and if so, how many different music on hold 
contexts?  Is Asterisk recording the channels?  What about meetme 
conferences?

Regards.
