AIUI, on (even semi-)modern kernels (like for the past 5+ years?), you 
shouldn't specify rsize or wsize at all.  Changing it from 8kB to 32kB 
would improve things, but removing it completely (as Jean-Yves 
suggested) should /significantly/ improve things.  The kernel can 
negotiate far larger/faster values dynamically, if you don't constrain it.
