I think you would probally be better off using VSync(1) for most timing
purposes ( it count's in hsyncs )
unless you want some really tight timing...
But checking the time for a single small function ( <1 Hsync ) can often
give misleading results as the effects of other bus masters / cache history
and dram refresh will sometimes give spurious results.

Cheers,

Colin.
