Not sure what happened - trying to investigate.

Btw, terbium usually shows more smooth graphs (ok, it's Itanic...)
(http://gcc.opensuse.org/c++bench-terbium/tramp3d/split-build.html)

I'll see whether I can find the time to setup C++ testing on czerny.

For terbium it's

  114 -> 124 between 141030.96758 (r216126) and 141211.32597 (r218621) 
(tester was down)
  123 -> 128 between 141228.22340 (r219074) and 141228.90737 (r219088)
  129 -> 160 between 150112.86585 (r219449) and 150113.55305 (r219508)
  162 -> 139 between 150119.02405 (r219836) and 150120.70780 (r219878)
  138 -> 127 between 150330.74477 (r221762) and 150330.46734 (r221770)
