Linux Realtek Gigabit NIC huge/high latency problem after sleep?

That is pinging to the gateway IP on the same switch, the same IP is pingable externally without any problems which makes me think the switch is fine.

This server hadnt' been accessed in days and at first responded normally and then started doing the above.  I did a network restart on the server and then it's been fine ever since.

Is it possible the NIC was put to sleep and then didn't come back properly, kind of like laptop WiFi after sleep?
