HI Hailin,
we just tried your test file with GCC 4.0.2, GCC 4.1.1 and Visual Studio 2005 (VC8). I used Cygwin for both GCC tests. My machine is Xeon 3.2 dual CPU. Both proxy and accessor implementation run at the SAME speed (release builds: -O2 for GCC and /O2 for Visual Studio). So could it be that GCC 3 is not doing a good in optimizing the code?
Apparently. So this is a non-issue then. Interestingly, the transformation interleaved => planar is faster than planar => interleaved. Is this also true on your platforms?
