You just throw back the problem to the Wine developers...
I think he means the shim is a less important factor on the loss of performance than some drivers that don't have high performance, but both will affect it(in other words there are issues regarding performance with higher priority than the ones coming from the shim).
Besides, at least from my understanding, what wine does is that when the wine dll is called, it calls a linux native function instead of a windows native function, at worst you get an extra function call in between. Whether the linux native functions or code within the wine dlls are optimized is of course another matter, not connected with inherent issues of the implementation.
