[LLVMdev] Size and performance figures for LLVM?

Can I trust those numbers?  For example, right now I'm looking at 
http://llvm.org/nightlytest/machine.php?machine=230.


"CVS checkout time" might be wrong, as LLVM is now in SVN.

This column also jitters heavily. However, it's not really 
important.


"Configure time CPU": is always 0, which must be a blantant 
lie :-)


"Build time CPU" is usually higher than "Build time wall". Isn't 
wall=cpu+system, so do we have negative system times here?  I 
could be completely wrong, but this looks strange. However, for 
the Dejagnu test, it hold's that CPU time < wall time.


Now I look at Chris' PPC box: 
http://llvm.org/nightlytest/machine.php?machine=153. And here 
suddenly "Dejagnu CPU time" > "Dejagnu wall time". Now I'm 
confused.
