Having a very odd time figuring out why queue priority doesn't seem to be working for me.

Test setup: Symmetric 1000/1000 connection, Hex S, Router OS 6.46.1

Two internal dhcp scopes 192.168.88.1/24 (lan) and 192.168.68.1/23 (guest)

Test results from running speedtest on both at the same time is a 50/50 split of available bandwidth (one device on 192.168.88.252 showing ~ 450 meg download/upload, one device on 192.168.68.2 showing ~ 500 meg download/upload) versus what I'd expect is the priority to give 100M to guest queue and remaining 900M to LAN queue as it has a higher priority.

I'm pretty sure I'm not doing anything stupid, fastrack isn't enabled. Verified devices IPs/etc.

Any ideas?

Not that it will matter, but you say guest is 192.168.68.1/24 but in queue you have a /23?

What does the ques say, do they show traffic / counters?

Have you tested 1 machine on its own, can it get full speed, may they cant and hence load is spread?

Fixed original post, as config shows it is a /23 and the IP is in the /23 range, yes, one client gets full speed when run alone of 900 meg, but when both run at the same time they split is ~ 450/each versus the priority 7 queue taking up 800 and the priority 8 queue getting remaining 100.

Anyone have any suggestions as to why this may not be working?
