Texture writer slow

anybody experienced the texture writer being veeery slow on some systems?
i use an athlon 3500+ 64bit system and geforce 6800gt graphics adapter. but saving the textures to disk is way slower than on my laptop or on an intel mac … same patch, same texture size …

thanks for any tips.
