Router MLXe8 - High ICMP response times

Hi,
Our MLXe8 router with BR-MLX-MR2-X and BR-MLX-10Gx20.

When I run ping commands from my PC to one of the IPs configured on this router, the ICMP time responses are high and vary a lot, times between 2ms and 40ms.

 

Pings to the management IP is fine in 1ms or less.

The pings are being executed from the local network.

The router CPU use is at 20%.

Is a normal behavior? The router changes the priorization of the packets?

Thanks
