hallow use thg4.4.1 on win8.1 with gamer-class computer (i7/16Gb)
work with clone of git repository of contiki (git+https://github.com/contiki-os/contiki.git)
clone have more then 10 subrepositories - git modules.
and i use stack of patches.
all operations now much slower vs thg 4.3.1. go to patches view, update to another revision takes about 1-3sec before actual operation is come.
it is slowpoke even on gaming computer. and realy irritating.
