[atlas] High inbound traffic causing packet loss?

Hello! I have just received an Atlas probe and I have been observing some weird readouts on the Atlas portal. Especially, occasional packet loss and considerable jitter, even to first and second hop destinations. I am surprised because even though I am a home user, I have a very stable connection (FTTH, 100/10 Mbps) and I've never experienced such connectivity issues. I've attached the probe directly to the ISP-provided switch that doesn't do IGMP snooping and since IP multicast is used for IPTV, high traffic (up to 50 Mbps) is occasionally flooded to all the switch ports. Taking into account that the probe is underpowered in terms of CPU, is it possible that it cannot handle such traffic and thus reports packet loss? If such is the case, I will move the probe behind a router to filter the multicast streams out. Best regards, Tibor Djurica Potpara
