The snipped is most likely from LV 2009 (as indicated from the upper right corner)

I couldnt get the reason from the image so I opened the snippet in LV2010 and there's a difference in the display of the buffer allocations (maybe because I enabled all of them - and additionally constant folding)

As you can see from the attached image, in version B, buffer allocation also takes place at the tunnel of the array on the for loop - so that's (very likely) the reason for the longer runtime of B.

Hmmm... In LV 2009, both loops match one another, and neither matches your image from LV 2010.  Turning all the dots on produces this:

Hm, this gets really strange now ... because I double-checked my snipped with the block diagram image that LV presents - just to make sure that all black squares are visible on the snippet. But I still feel there are some dots missing when I compare to the LV2k9 snippet ...

Man, that black dot is nearly impossible to see on the dark blue of the tunnel.  And even using Refresh to cause them to flash doesn't help so much.

Sounds like we need another new idea like the one with Pink coercion dots on pink cluster.  http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Coercion-dot-color-change-if-terminal-is-pink/idi-p/12...
