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?

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
