I ran it in Pharo 4 (40616) because method putSource:inFile:withPreamble: no longer exists in Pharo 5 and results are:
Desktop...
all: 13.062 per second
compile: 6,603 per second (why the hell is there comma as separator and not dot?)
store: 13.431 per second
add: 406.400 per second
Notebook...
all: 210.180 per second
compile: 12,007 per second
store: 454.818 per second
add: 806.239 per second

But I think taking the compile: method apart tells a better story
~~~~~~~~~~~~~~~~~~~
code := 'a'.
method := Object compiler
source: code;
requestor: nil;
failBlock: [ ^nil ];
compile.
all := [
Object compile: code.
].
compile := [
Object compiler
source: code;
requestor: nil;
failBlock: [ ^nil ];
compile.
].
store := [
method putSource: code inFile: 2
withPreamble: [:f | f cr; nextPut: $!; nextChunkPut: 'Behavior method'; cr].
].
add := [
Object addSelector: method selector withMethod: method notifying: nil.
].

150x slower disk operations? -_-
I mean for normal programming this doesn't really matter, but when we are
downloading even medium-sized package it takes ages to process...
