Hi MikroTik Community,
I am configuring a hEX / RB750Gr3 router on RouterOS v7 to balance heavy local bandwidth usage (downloads, video streams) while maintaining low latency for real-time mobile and web arcade sessions across local LAN clients.
Currently, when multiple devices on the local subnet trigger parallel TCP downloads, latency sensitive real-time interactive traffic—like users accessing arcade game sessions or guides on worms zone , experiences significant ping spikes (bufferbloat) going from ~20ms up to 250ms+.
I am looking for best practice guidance on the following RouterOS queue configurations:
-
FastTrack vs. Mangle Rules: Since FastTrack bypasses the firewall mangle rules and queues, what is the most efficient way to maintain FastTrack for high-speed local throughput while still prioritizing UDP/TCP packets for latency-sensitive devices?
-
FQ-CoDel / CAKE Setup: Is applying a CAKE queue type on the WAN interface directly the recommended approach for eliminating bufferbloat on asymmetrical broadband connections (e.g., 100Mbps Down / 20Mbps Up)?
-
Should priority marking (
action=mark-packet) be based on destination IP lists, or is DSCP/CoS classification more reliable for local LAN traffic?
Looking forward to your suggestions and queue configuration examples. Thanks!
