[Feature Request] Graph for PCIe bus load

[adlerweb]

nvtop already displays current PCIe link speed as well as current RX and TX values. Wouldn't this be enough to also generate a bus load percentage as metric for graphs? This way it would be easier to spot bottlenecks related to data transfer.

Hello,
That does not seem too difficult to implement.
I guess that we can use the theoretical limit for PCIe bandwidth as reference for the percentage calculation.

@Syllo as I am using a gpu connected through an external enclosure (pcie4x4) I am trying to figure out if I can squeeze some more performance out of it and would love this information in that pursuit. I was wondering though, would it be possible to add a button to run a small test for what the max throughput currently is? That way there could be a percent usage of theoretical speed and a percent of tested/verified speed.

Thank you for all the work you put into this.
