hello
i found a other best and faster resynthetiser plunin for gimp
Textureops plugin
http://www.logarithmic.net/pfh/textureops
Sharpen Feathering: increases the contrast of feathered regions of a layer to counteract the reduced contrast effect.
Make Seamless Texture: is a modified version of the standard GIMP plug-in “Make Seamless” that produces a more uniform output by adjusting for reduced contrast.
Synthesize Texture: is a script for synthesizing a tilable texture image of arbitrary size from a sample. It does this by randomly piecing together patches from the sample, disguising the edges using Sharpen Feathering.
soo 
All TextureOps plug-ins are very much faster than Resynthesizer mostly because they are so damn simple.
but this is SOURCE CODE and I don’t found windows binari or exe file on the internet 
so if you have a compiled version post here PLEASE
THANX
