I'd start with stracing the python process to try and see if it is something wrong or maybe there is a sleep(1) command done there. Other than that I can only think about look at Tkinter code and changing it to print what it does so you can trace it when it runs to see what happens. It is also possible to compile the Tkinter.so object with debug symbols and use gdb to just print at breakpoints and continue immediately, though latency of break points will be higher than prints.
