The effect of the new buffer cache code on the vnode cache has already been
noted. I would expect the drag you're experiencing to be largely eliminated
if you'd revert the maximum memory use for the buffer to historic levels,
i.e. to around 5% of physical memory. To verify that this is the case,
could you do
`sysctl -w vm.bufcache=5'
and see if that makes the symptoms go away?
