Mikrotik CSS326-24G-2S+ Extremely Slow after 2.9 Upgrade

I have two systems connected to the switch via 10GbE. Before the upgrade I was only able to get to ~2.5Gbps via iperf between the two. I assumed that was just an issue with the configuration on the clients but have been digging a bit and it seems to be more an issue with the switch itself. Directly connected to each other the systems are getting much better speeds (~6gbps).
I'm at a loss now after upgrading the switch to v2.9. Both are showing up as 10G on the switch. Is there any update to this issue? Is this switch just not capable of giving full 10GbE from the two 10G ports?!
