I have two examples where TM2 is slower compared to TM1.
1.
I think this has been mentioned before but TM2 takes significant longer time to syntax highlight large files compared to TM1. An example is this file from the D standard library:
https://raw.github.com/D-Programming-Language/phobos/master/std/datetime.d
It might be a bit extreme, it's around 34 000 lines of code. If I open that file and then jump to the end of the file. It takes TM1 around 5 seconds until the code has syntax highlighting. In TM2 it takes around 15 seconds.
2.
TM2 is also slower on auto completion for some files. Here is one example:
https://github.com/d-widget-toolkit/dwt-mac/blob/master/dwt/widgets/Display....
If I put the cursor at line 2111 at, type "o" and press escape to do auto completion. In TM1 I immediately get a result. In TM2 I get a result after around 3 seconds.
Is there anything that can be done to increase the performance in these two areas?
