I found the memory performance of newer kernels are quit poor on an EVM-Omap3 board. It works with 2-6 times performance on the old 2.6.22 kernel from TI's PSP. Possible reasons: - problem in config the kernel (did omap3_evm_defconfig) - problem in kernel - kernel expects some settings from uboot, which are not done there I have tried the 2.6.29rc3 (from TI's PSP) and the 2.6.31 from git-tree. Both behave quite simular: Transport in MByte: memcpy = 204.073, loop4 = 183.212, loop1 = 81.693, rand = 4.534 while the 22 kernel: memcpy = 453.932, loop4 = 469.934, loop1 = 125.031, rand = 29.631 Can someone give me help or can at least confirm that?
