How to measure USB cable data transfer speed, charging speed

I have a 2m USB-C to USB-C Thunderbolt cable that was advertised as 100W fast charging with 10Gps data transfer.

I suspect that it is neither of these things.

Is there some way to measure the above specs precisely on my 2023 Macbook Pro? For example, through an app or checking system settings?

I'd appreciate responses that are on-topic (rather than discussing logos and packaging).

Thanks heaps for your help!

MacBook Pro 15″, macOS 11.7

I expect you want to connect something with this cable you already own.

EXACTLY what devices are you intending to connect ?

My MacBook Pro with other devices.

My Mac is only 3 months old and high-spec, so definitely able to handle big data loads.

Not trolling.

The reason this is off-topic is that I already own the cable and have discarded all packaging, logos, etc.

My requests to stay on-topic nevertheless fall on deaf ears!

Any more help?

To be clear, I'm wondering if there's some kind of software that can measure this.

Cheers,
