I am trying to size my VM installation and I currently have it installed on a VM with 2GB RAM and 1 vCPU.
I notice when I run top, I quickly hit 80-90% us% and spike to about 10% on the wa%
I know I am on a 6+ year old Server 2016 server installation ( I have a new 2019 shipping )
I was thinking of giving it another vCPU but wanted to lean out the modules first as I think this should be best practices anyways.
I currently have a simple setup.
(3) trunks: contiguous US, International, e911
(3) extensions ( simple Ring Group to FXS ports on an Adtran; no conferencing, queueing/agents, etc )
(3) DIDs ( 1 of which is mostly used )
(2-4) concurrent calls.
I will be increasing this to the following:
(24) extensions ( 5-6 Ring Groups to FXS ports on an Adtran; no conferencing, queueing/agents, etc. )
(~7-10) concurrent calls. ( 24 max as the adtran only has 24 FXS ports )
I was thinking of disabling isymphony, zulu, and CID Superfecta.
Is there any other modules that should be set to disable to keep the background processes from firing?
