What that is telling us is that you are receiving a large amount of data at a slower rate (from the server) than necessary to keep the game running smoothly :

- "In : 576" is the size of the incoming packets from the server.
- "7.05k/s" is the rate in kilobytes (per second) that you are receiving the packets of data from the server.
- "33.3/s" is the times per second your computer is receiving info from the server.

The amount of "in" updates should never exceed the servers tickrate (in this case, 66). As you're experiencing no loss or choke, then no packets are being lost or not received by you. That means that you are taking in and sending all the packets that you should be, but there is too much going on, which causes this lag spike in your game. You see, you're taking in too much and sending out too much all at the same time, and your network can't handle that.

I think that's right?
