XE75 Pro high latency
Hello,
I have a strange problem with a Deco XE75 Pro. The image below is my current seutp. If one of the clients connected to the switch 10/100 satures all the bandwidth, for some reason my desktop connected to the XE75 Pro gets very high latency (from 8 ms to 8.8.8.8 to 120-130ms) and the speedtest drops from 900 Mbps to 50-100 Mbps. As soon the saturation between the two switches stops, the problem disappers. How can this be the case if my desktop is connected directly to the Deco XE75 Pro ? If I try to enable QoS to some values below 100Mbps (e.g. 40-50), the problem is slightly better but still it is something that I would not expect to see at all. All clients are connected via ethernet, even the Deco E4 that should not be involved in handling the traffic.
Does the Deco E4 affects the performance of the whole network if the link between the two decos gets saturated ?
