We did make a tool that could poll that fast and do accurate timestamps 
a few years ago and discovered that the routers
did not update theirs MIB's that often. Some platforms would not copy 
statistics from the interface cards more often than a few (5)
seconds. Single processor architectures though seemed to have subsecond

did not publish, but the perl-scripts are intact.
