Obviously, it is slower, there is a whole image that needs to be loaded, etc.

$ cat test.st

#!/Users/sven/tmp/pharo4/pharo-vm/Pharo.app/Contents/MacOS/Pharo --headless /Users/sven/tmp/pharo4/Pharo.image st --quit

FileStream stdout nextPutAll: 42 factorial asString; cr.

$ time ./test.st
1405006117752879898543142606244511569936384000000000

real �� ��0m0.644s
user �� ��0m0.516s
sys �� �� 0m0.067s

So about half a second overhead.
