Benchmarking actual PCIe bandwidth

I would like to know if it is possible to measure the actual PCIe bandwidth. I know there is stuff like Intel’s PCM and I think there are tools in the CUDAtoolkit but I would like something that is more suitable for DMA. I heard there is a counter on the PCIe switch that counters the data going through the switch. If anyone knows more about this could someone let me know.

Basically, I would like to test the speed on PCIe when using DMA between e.g. GPU and ram.

Thanks.

Hi Kepler3141,

We don’t have the tool to perform the test you want, but could help to resolve on the performance problem you met. May I know if any specific issue on your use case?

Thanks
