[asterisk-dev] Asterisk stress test

[能功 杜]

dear all,
       i try use two asterisk do stress testing. my method like this :
i wrote a application for Asterisk Server A name app_silence. the main code of this application as following :
/************************/
if(chan->_state != AST_STATE_UP){  ast_answer(chan); } ast_channel_start_silence_generator(chan);
 while(ast_waitfor(chan, -1) > -1){  f = ast_read(chan);  if (!f)   break;  ast_frfree(f); }/*************************/
 
then i configure Server B as a iax friend of Server A.
[test]
host = server_A_ip_address
secret = test
type = friend
context = test
 
i use call file to create calls.
callfile like this :
/*************/
Channel: IAX2/testMaxRetries: 2RetryTime: 60WaitTime: 30Application: echo
/*************/
while Server A i configure a default dialplan
exten => s,1,answer
exten => s,2,silence
 
so when i move the callfile to server B's outgoing. it create a call. Server A call server B.
in this way ,i can create many calls between two severs.
 
my question is : when i create 3 calls between the two servers,server A's loading is very heavy ,
CPU always 99% and load average is about 2 or so.
what's wrong ? is this the correct way to do concurrent-calls testing?
 
BR
