Cisco Aironet 1815t - awful performance

We've deployed a cisco WLC 5500 with some 1815t's as a POC/Test to our remote offices.

They're doing the standard stuff with a tunnel to the controller in our datacenter, where we then route it to the internet/lan.

We're seeing awful performance from these devices though.

One site that has a 80/10Mbit connection (~30ms rtt to wlc controller) is getting 9/8Mbit when doing an iperf test.

Zero packetloss, just awful performance.

I'm about to open a tac, but thought you guys might have some input.
