Optimize WAN built with Cisco 1700 series routers
We have a 2mb private line between our two offices and a Cisco 1700 series router at either end. It's a little slow these days and was looking for some advice as to how to minimise unncessary network traffic such as broadcasts from passing other the WAN link.
Can anyone offer any suggestions?

Are the two sites on separate subnets? That'd be the quick way to keep broadcasts from propagating.

Well, the HQ is on 172.16.16.0 and the Branch office is 172.16.32.0 both with subnet mask of 255.255.255.0
That'd put you on separate subnets then, and a broadcast from either side, to 172.16.32.255 or to 172.16.16.255, by default, shouldn't travel across the router. Are the 1700s the actual gateways or are they used only to terminate the private circuit? Whereever your actual router(s) are, you'll want to make sure someone hasn't turned on a 'Helper' rule that enables propagation of broadcasts. Again, by default, most routers won't pass broadcasts.
Out of curiosity, how have you determined that traffic going across is broadcast based?

The 1700s are the gateways for each office and were installed by BT some years ago.
I haven't really determined that it's broadcast based.
The other possibility was Internet traffic as the branch office use the proxy server in the HQ for their internet access.
