[Freeswitch-users] mod_skypopen - performence and capacity.

Fri Sep 10 17:55:37 PDT 2010

You must run skypes and at least one FS instance on one EC2 instance,
depending on the performance, you could run 1 FS + (1 upto 64 or
perhaps 128) skype instances on 1 EC2. But note that if one skype
instance crashes it may cause the entire FS/skype unstable(although
there are tricks and solutions), so, instead of 1FS+128skypes per EC2,
you might want, say, (1FS+24Skype) * 5EC2. As giovanni said, you
should try with real world test to find out the best combination.
