Hmm, I would like to know the answer as well. As far as I can tell, the problem is given by transforming the String into Text, and this is done by PluggableTextMorph. Does anyone have a clue on how to proceed when we want to display a large amount of text in a Morph? Cheers, Doru On Mon, Jul 23, 2012 at 5:36 AM, Usman Bhatti <usman.bhatti@gmail.com> wrote:
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
