I'm having some sort of similar scenario on my RB750Gr3, after the same RC update I get some mixed bag of performance, despite "IP -> firewall -> Connections" show my IP sessions with the fasttrack flag, I can only saturate 70% of my gigabit pppoe line, before it was saturating just fine at over 90%. The profiler shows the firewall process eating up the resources.
I disabled all firewall and routing rules except the barebone fasttrack rules and the problem is still there. I get 100% load on the second core(both threads), while the first core is at 30% load on the first thread, the second thread being inutilized.
I hope the next RC will fix this issue with fasttrack. Before this update, fasttrack worked without issues, both cores had 40-50% load while using the full bandwidth.
Edit: I fixed my fasttrack issue by disabling learning on the lan bridge on all ports. Something in the last update broke something, don't know, now I get the mac-address table in the bridge hosts section.
