Description
We dug into cassandra code and found out SimpleSnitch was not working with DynamicSnitch. Specifically, the code turns a slow node into a remote node and network topology works with that. We also had to move to LOCAL_QUOROM and finally we have dynamic snitch working. To test this, we basically told the NIC using the "tc" command to slow every packet down by 500ms on node 2 (out of 4 nodes). We finally have a blazingly fast client with node 2 slowed down. If we do QUOROM, the issue comes back and the client is slow again. Same with SimpleSnitch. To reproduce, run a 4 node cluster and use "tc" to give every packet a slowdown of 500ms.
