pharo vs. java

by Nicolas Anquetil

I have been doing some file intensive activities and found my program to be VERY slow (see at the end). Just to be sure I ran them in Java and found it was much faster So I did a small test: --- [10 timesRepeat: [i := 0. '/home/anquetil/Documents/RMod/Tools/workspace/Blocks/jfreechart-0_9_0.mse' asFileReference readStream contents do: [ :c | i:= i+1]. ] ] timeToRunWithoutGC. --- result = 12.932 sec similar thing (as far as I can tell) 10 times in java: 1.482 sec. --- public static void main(String[] args) { int length =0; try { String filename = "/home/anquetil/Documents/RMod/Tools/workspace/Blocks/jfreechart-0_9_0.mse"; String content = new String(Files.readAllBytes(Paths.get(filename)), "UTF8"); for (int i=0; i < content.length(); i++) { content.charAt(i); length = length+1; } } catch (IOException e) { e.printStackTrace(); } System.out.println(length); } --- Because my program is MUCH slower (see at the end) in Smalltalk than in Java, I did another experiment: --- [1 to: 10 do: [:i| 1 to: 100000000 do: [:j | String new] ] ] timeToRunWithoutGC. --- result = 33.063 sec and in java: 4.382 sec. ---[10 runs of] public static void main(String[] args) { for (int i=0; i < 100000000; i++) { new String(); } } --- Concretly, my need was: Take 2600 methods in a Moose model, take their source code (therefore reading files), for methods longer than 100 lines (there are 29 of them), go through there code to find the blocks (matching {}). In smalltalk it ran > 12hours and I had processed 5 methods of the 29 long ones I reimplemented in Java (basically, just changing from pharo to java syntax) and it took 1 minutes to compute everything ... :-( On the good side, it was much easier to program it in smalltalk (about half a day to think about the algorithm, experiement, implement, test) than in Java (another 1/2 day, just to recode the algorithm that already worked). nicolas

That is great. And you even have a solution for your problem. Both of these will remain in the image for Pharo 4, so that solution will work. However, the menu is also the entry point for newcomers. We should not bombard them with choices that distract them from their goal of experiencing Pharo.

Re: [Pharo-dev] Workspace and GTPlayground menu item

by phil＠highoctane.be

My usage pattern is not that. I have GTPlayground disabled in the settings and GTInspector enabled (Pharo3 here). And I've made a keybinding to open the playground. And use Alt-o Alt-w for getting a workspace. So, I do use both. And not "one or the other".
