[asterisk-users] Asterisk 1.4 Vs 1.6 Vs 1.8

[Tarek Sawah]

Hello 
i am not sure if this has been discussed before.. 
i have an asterisk 1.4 server that i managed to test it with 500+ concurrent calls and hit 800 concurrent calls with no problem CPU USAGE 90% 
i wanted to upgrade to 1.6 .. i did and when tested it .. the server crashed at 100 concurrent calls. 
my question is .. is there a different in resource consumption between all versions? how come 1.4 could handle over 500 calls while 1.6 crashed at 100?
please advise?
