Isn't the overhead to map/unmap the buffer fairly high? Why don't you keep the buffer mapped?
That was what I was getting at. If the pool is shared amongst drivers then the buffer has to be unmapped before being recycled (in case it's allocated by a different driver) thus blowing away most of the advantage of loanup.
