Hi, I've done here some tests between two MVME6100, while updating the 6100 BSP for our embedded Linux distro. Depending on the buffersize, alignment, VME and PCI FIFO settings we have (without further optimizations) throughput rates ranging from 100MBps up to 168MBps. I think some tuning could still be done.
