I read something similar on all the forms about the CPU. I have to admit, I posted this just after I set the settings to 75. Interestingly, taking a look this morning, I can see that I’m now processing between 300 & 400 messages per second on the output with around 1200 on the input (peak)
So the setting did do something positive I guess? I saw a similar thing on reddit and on the forms here too:

The thing that bugs me is that I can’t get the CPU to peak anywhere near 100% (I’d be satisfied if I could see the CPU or memory pegged)
