We all know about the wonderful benchmark called Apache vs. Yaws, http://www.sics.se/~joe/apachevsyaws.html

However, there are some sceptics who say that Apache will outperform Yaws when sending files/large files because Apache uses sendfile which runs in kernel space. So my question is: How will Yaws perform in the above benchmark if each process needs to send a 10 MB file?
