Cisco 3850 - Slow Intervlan Routing (1 MB/s) on 1 Gig Interfaces

I have a new almost stock installation of a Cisco 3850 doing intervlan routing (I don't even have any security between VLAN's yet).  Any file transfers between VLAN's are very slow (no more than 1 MB/s).  File transfers within a VLAN are fine.  

I am running the latest IOS software for this device.

Any thought on what could be causing this issue?

The config:

Thanks for your reply.

IP CEF is enabled on all interfaces (sample sh cef interface command):

SW-SR-3850#sh cef interface g1/0/1
GigabitEthernet1/0/1 is up (if_number 5)
  Corresponding hwidb fast_if_number 5
  Corresponding hwidb firstsw->if_number 5
  Internet Protocol processing disabled
  Hardware idb is GigabitEthernet1/0/1
  Fast switching type 1, interface type 146
  IP CEF switching enabled
  IP CEF switching turbo vector
  IP Null turbo vector
  IP prefix lookup IPv4 mtrie 8-8-8-8 optimized
  Input fast flags 0x0, Output fast flags 0x0
  ifindex 4(4)
  Slot 1 Slot unit 1 VC -1
  IP MTU 0

Any other suggestions?

Hi All,

This is a bug in the IOS for the landbase licensing.  

We moved to a evaluation license and a fix should be out next week (hopefully).

Buggy software:

 WS-C3850-24T       03.02.01.SE       cat3k_caa-universalk9

Thanks for all your help
