[Pharo-project] Fwd: [Lsehub-staff] Fwd: Performance of text presentation in Glamour

Aug. 12, 2012

      Hello people,
The issue is getting a bit on our nerves so if someone can look into it
during the next week, it'll be great. Me and Guillaume tried to have a look
but it goes deep into the morphic layer of pharo and we do not have much
time to allocate to this issue.
Someone with a better knowledge of morphs can provide a quick fix?

Here is a link to the image that contains the scripts in its workspace to
analyse the problem.

Let me know if you have problem with the image.

tx in advance,
Usman

Subject: Performance of text presentation in Glamour
To: Moose-related development <moose-dev@iam.unibe.ch>
Hello all,
I am working with text presentation in Glamour: the browser is used to
show the contents of code files. I noted that the time to display the
contents of a file (almost) exponentially grows with the size of the file.
So, performing tests on files of three different sizes, I obtain the
following response times (using Pharo profiler):
1000 lines     2s
2500 lines     11s
3500 lines     23s.
So thats quite lot for me where I occasionally have files with 2K lines
and I may need to browse their contents rapidly.
Running my test script with the profiler in Pharo, I get this tree. I
see that the message fromString: method is sent to Text class several times
and that takes about 96% of the time (in all test cases). Any hints on how
to reduce the number of times the method is invoked by glamour?
tx in advance,
Usman
