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
