The performance of memory transfers depends on many factors, including the size of the transfer and type of system motherboard used. We recommend NVIDIA nForce motherboards for best transfer performance. On PCI-Express 2.0 systems we have measured up to 6.0 GB/sec transfer rates. You can measure the bandwidth on your system using the bandwidthTest sample from the SDK. Transfers from page-locked memory are faster because the GPU can DMA directly from this memory. However allocating too much page-locked memory can significantly affect the overall performance of the system, so allocate it with care.
