> There are many high-performance DMA devices supported in DPDK now, > and these DMA devices can also be integrated into other modules of DPDK as > accelerators, such as Vhost. Before integrating DMA into applications, > developers need to know the performance of these DMA devices in various > scenarios and the performance of CPUs in the same scenario, such as > different buffer lengths.

This patch > introduces a high-performance testing tool, which supports comparing the > performance of CPU and DMA in different scenarios automatically with a pre- > set config file.
