Marcel ,

 I forgot to mention that. This option in node is actually 
--max_old_space_size according to the node's manpage, but not work for me 
when greater than ~2G.

During my search and test, I found this option only useful to remove the 
soft limit in old days (say node 0.6). It likely because that the old 
version v8 has an 512MB limit on 32bit and 1G limit on 64bit. 
But latest 64bit v8 seems no longer holding this soft limit. So it may not 
work for me, unless I miss something.
 
My test commands are:
node --max-old-space-size=8192 speedTestRaw.js 
node --max_old_space_size=8192 speedTestRaw.js

Both make no difference, and terminate about 10M.
