No, not that one (also interesting), I was talking about this one (which as far as I understand is unrelated):What I know is that large memory allocation (128k and more) using the malloc() command, uses in turn the mmap() command, in a way that is much, much slower on OSX than on Linux.
It's unrelated in some way, but anything slowing down the CPU can cause the other one that I just stated (the 91% CPU that becomes 250% or whatever, in my example). It's just a matter of asking a little too much from the codec.
It seems that the memory allocation problem is much more of a problem for GridFlow than for GEM, but I haven't measured.
