With the limited information you've given, I'd put money on microbursts. For all your traffic higher than 1Gbps, that data has to get buffered on egress ports of devices. Eventually, traffic will get dropped to make room for new traffic. This is far worse in places where you may also have 100Mbps ports.
"doesn't seem to be affecting the wan side of my router which connects to peers through the same switch" this was the kicker to me, combined with the "~2Gbps" line.
