Main Contributing Factors in Sound Board Button Delay?

Hello, I am trying to figure out how to scale sound board. However it seems I always get to a point and agents complain of button delay.

1) Is it DB Load?
2) Is it Web Load?
3) Is it asterisk dialing to hard?

Is it in crontab this needs to be run more aggressive? "/usr/share/astguiclient/AST_flush_DBqueue.pl"

I have tried,

11,26,41,56 * * * * /usr/share/astguiclient/AST_flush_DBqueue.pl --seconds=240 -q
11,26,41,56 * * * * /usr/share/astguiclient/AST_flush_DBqueue.pl --seconds=500 -q
11,26,41,56 * * * * /usr/share/astguiclient/AST_flush_DBqueue.pl --seconds=900 -q

However, it's like if this were a graph lines cross at some point where nothing I do seems to help? Maybe it is channels and asterisk? Dialing harder is less channels for audio insertion? I have always wondered. Thanks for looking!

thats most likely the web load

Not sure it is. I have tried putting separate web server. Its like the harder you dial, the more button delay. Because the way the audio looks like it opens another channel each time you press a button?
