<div dir="ltr">Hello Simon,<div>� �Cent OS takes much lesser traffic than I have on Ubuntu. I migrated 5% cpu traffic from ubuntu and It caused 15% cpu increase in Cent OS. I goggled and noticed quite similar questions but didn't find any solutions. If there are a few knobs that I can tune, �I would be happy to test it out.�</div>

I'm afraid there isn't a good way to see which parts of the broker are busy at the moment (we hope to add something along these lines in a future release).<br>
<br>
I'm suspicious of the idea that it's distro-related though. Is the CentOS server really performing the same workload as the Ubuntu server?<br>
<br>
To get to the bottom of this you'd have to gradually take bits away until you see the CPU usage drop - stop connections, disable plugins and so on.<br>

Hello There,<br>
<br>
� � Reg my previous message, is there anyway to dig into the high cpu<br>
usage issue? With similar configs in Ubuntu & Cent OS, Cent OS takes lot<br>
more cpu for beam.smp process. I switched log level to "info" but<br>
noticed nothing unusual.<br>
<br>
Any help would be appreciated.<br>
