Many thanks to all responders. It turns out that there is a winbugs update available, which defines a new version of inprod, inprod2. Using inprod2 the vectorized code runs in about the same time as the "scalar" version.
On the print problem: the issue here turns out to be that the arm package (or one of the packages it loads) resets digits to 2. So the solution is to reset digits ( options("digits"=5) or whatever) after loading your packages.
