Perforrmance and translateXXXX methods [message #223732] Wed, 04 October 2006 17:10 Go to next message

Hi All,

When opening a diagram with about 50 nodes and 700 lines, my GMF and GEF
based graphical editor took about 20 seconds. The execution profiling data
shows the top three time spending methods are Figure's
translateToAbsolute(), translateToRelative() and translateToParent().
I am wondering how to cut down this. Is it something to do with
coordinate system ? Any help will be appreciated.

Li

some other method that is taking all the time. Do you have more info? What
about invocation count? Even a really fast method takes a lot of time if you
call it millions of times.
