Thanks for the result.  I'm quite dubitative now : I thought this was
a fact that RELENG_5 have worse performances than RELENG_4 for the
moment, partly due to lack of micro-optimizations.  There have been
indeed numerous reports about weak performances on 5.x.  Seeing your
results, it appears that RELENG_4, RELENG_5 and CURRENT are in fact
very close.  What should we think then ?
