I also notice very low performance of gtk on windows. my program draws
lines and points and on linux it takes max 8% of CPU but on windows on
the same machine it takes 100% CPU and it flicks. 

I don't know how to cope with it. You could also try gtk 2.6 from Tor's
site. I use this switches when compiling my app
FLAGS = -Wall -O2 -ffast-math -fomit-frame-pointer
-fexpensive-optimizations -fstrength-reduce -mno-cygwin -mcpu=pentium
-mms-bitfields -mwindows
