Re: [Pharo-users] speed of streams?

You are measuring image startup time, not the actual code. 'bar.txt' asFileReference writeStreamDo: [ :out | 10000 timesRepeat: [ out << Character alphabet; crlf ] ]. [ 'bar.txt' asFileReference contents ] bench. "37.296 per second" [ 'bar.txt' asFileReference contents ] timeToRun. "0:00:00:00.022" So reading a 260Kb file is pretty fast. Image startup is 0.5 seconds at best (headless, linux) in my experience. > On 15 Mar 2015, at 22:34, stepharo <stepharo(a)free.fr> wrote: > > Nicolas asked me the following questions and I was stuck :) > > Stef > > I have been doing some file intensive activities and found my program to be very slow. > Just to be sure I ran them in Java and found it was much faster > > So I did a small test: > --- > i := 0. > '/home/anquetil/Documents/RMod/Tools/workspace/Blocks/jfreechart-0_9_0.mse' asFileReference readStream contents do: [ :c | i:= i+1]. > --- > > 10 times with TimeProfiler : 14.436 sec > 10 times as a script passed to pharo-vm-nox (latest 4.0 image) : 16.07 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); > } > --- > > is this known ? normal? > > nicolas > > PS: time for java and pharo script or measured as: > $ for i in 1 2 3 4 5 6 7 8 9 10; do time run-experiment; done > >

speed of streams?

by stepharo

Nicolas asked me the following questions and I was stuck :) Stef I have been doing some file intensive activities and found my program to be very slow. Just to be sure I ran them in Java and found it was much faster So I did a small test: --- i := 0. '/home/anquetil/Documents/RMod/Tools/workspace/Blocks/jfreechart-0_9_0.mse' asFileReference readStream contents do: [ :c | i:= i+1]. --- 10 times with TimeProfiler : 14.436 sec 10 times as a script passed to pharo-vm-nox (latest 4.0 image) : 16.07 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); } --- is this known ? normal? nicolas PS: time for java and pharo script or measured as: $ for i in 1 2 3 4 5 6 7 8 9 10; do time run-experiment; done

Git is too complex for me, I feel dumb so this is good to know that you guys are spending time on that.

Re: [Pharo-users] Woden-Roassal missing classes/examples not working

I do not get why ConfigurationOfWoden cannot handle all the rest. We will fix that with JB. Users should load a project in one click! I do not get what is complex in that idea.

ExtendedNumberParser now has its own repository

by stepharo

Hi I did not want to lose the work of Nicolas Cellier around alternate number parsers so I went back in Pharo 30 and packaged them as a separate package (may be it was already done but I could not find it). All the tests are green in Pharo 40. So I hope that everything is ok :) MCHttpRepository location: 'http://www.smalltalkhub.com/mc/PharoExtras/ExtendedNumberParser/main' user: '' password: '' I did a configuration and published the code in the meta repository for Pharo 40. Thanks Nicolas Cellier for the original code. Stef (I believe that we should pay attention that doing is difficult and we should not lose good assets) Mariano can you verify if you can load it?
