Hi all, We are evaluating FreeSWITCH as a replacement for our current commercial SBCs - before anyone points it out, we need a B2BUA for sane CDR generation (aka billing) and there is some ideas for future functionality that would leverage more of the FreeSWITCH platform. That being said we are currently forcing static IPs, disabling registration and presence and setting inbound-late-negotiation for the sip profiles. "Client" gateways are being authenticated using remote IP ACLs and a dial string prefix. The dialplan looks like this... http://dpaste.com/196561/ The box in question has two Intel Xeon 5130 dual core processors w/ 4 GB Ram (being upgraded, trying to figure out how much ram we should have). Disks are 4x 15k RPM SCSI in a Raid 10. Operating system is CentOS 5.4 x86_64. FreeSWITCH is being started with "-nc -nonat -waste". What things should we be looking at to squeeze as much performance as possible out of these boxes? Thanks, Max [root@fs-sbc02 freeswitch]# vmstat 3 procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 4 0 112 25220 237172 2829060 0 0 0 10 2 2 0 0 99 0 0 0 1 112 48412 236400 2800596 0 0 0 2408 13298 212312 20 14 63 3 0 25 0 112 46024 236444 2803632 0 0 0 1172 13245 219590 15 13 69 4 0 32 0 112 45784 236512 2808200 0 0 0 2839 13153 164973 21 14 61 3 0 63 1 112 37880 236544 2811808 0 0 0 2884 13048 199455 21 16 60 4 0 1 0 112 37488 236588 2815612 0 0 0 4000 13201 142378 16 17 50 17 0 0 0 112 42648 236616 2818376 0 0 0 2125 13171 107533 13 13 70 3 0 1 0 112 47904 236636 2820704 0 0 0 1989 13400 86644 10 11 72 6 0 6 0 112 50372 236652 2822200 0 0 0 1585 13339 69289 8 9 78 5 0
