Internet Speed - CPU Limited

[Weggy]

Hi,

I don't know if this is known or perhaps expected but I thought I'd mention it.

When performing an Internet Speed test (Adaptive QoS > Internet Speed), on my ASUS RT-AC5300 over a 900Mbps down 110Mbps up line. The performance appears to be CPU limited and for myself tops out at around 325Mbps.

I can confirmed high speeds can be hit by testing on other devices (i.e. PC).

iirc it's an issue with TrendMicro services being enabled and not a cpu bottleneck. I think you need to withdraw all permissions from TrendMicro services under Administration -> Privacy to make it work properly.

Yes this is a known limitation.

Fair enough. Thanks for the info.

Just so I'm clear, this issue with speed is only when using the Speedtest applet in the QoS tab and not an overall speed limitation with the router?

Correct.
