 Hе флейма ради, а информации во имя. Тем более, что ничего
 сверхестественного этот бенчмарк не показывает. А кому-то может быть
 интересен.
 
 Вот что пишет по поводу него Мэтью Диллон (Matthew Dillon):
 
 Pretty comprehensive.  The numbers are about what I expect.  5.x will
 do better with pure userland cpu tests simply because it has a more
 recent GCC installed, and will do worse on benchmarks requiring lots
 of kernel interaction (like small-block writes) due to higher kernel
 overheads.  The 5.x pipe code is very well optimized so the results
 there make sense, and the 5.x network code has a number of fixes in it
 which 4.x never got.
 
 I think DFly is in pretty good shape performance-wise but there is
 at least one mbuf related patch we ought to throw in.  Also, the
 recent token code work has not been well optimized yet but I don't
 know
 how much that will impact things relative to what we had before.
