Comment (by arma):

 Replying to [comment:6 iang]:
 > I also noticed a little while ago that the way the TAP cells are
 currently farmed out to cpuworkers may not be the most efficient way we
 could do things.  There are quite a few system calls happening for each
 TAP cell right now; something more clever could surely be done.  With
 ntor, the system call overhead would likely be a substantial fraction of
 the total processing time.  But, as above, this would be a separate
 ticket.

 Ian, can you explain in some more detail? We should explore doing this in
 0.2.5. If you have enough details to have a concrete suggestion, please
 make a new ticket out of it.

 Thanks!
