Any shoutbox addon with low cpu usage?

[Inferno Dragon]

Hi,
I was using the vbshoutbox 2.0 by ZT, but today I received a waring from my web host about the high server usage of vbshout.php. now I am looking for a alternative.. I know there are few other shoutbox addons are available for vbulletin 3.6 but I want to know if any one suggest me a lite vbshoutbox feature which don't consume much CPU?

Thanks,

All things that use AJAX consume CPU resources...Try turning down the refresh rate a little :).
