The USB hub is recognized by the host as a distinct USB device. So inserting a USB hub (which does act as a repeater) will add latency, not reduce it. A repeater uses a receive, store, and forward method, so there is no way it (or any device) can reduce latency as you ask.
Similarly, you may ask, do USB hubs add latency gaming?

Similarly, do USB hubs add latency Reddit? No. It's already going through a hub on your motherboard which doesn't increase latency either.
Keeping this in view, does USB hub reduce performance?
As stated, so long as sufficient power is running through every device connected to the port, no problems should occur. Just my case as an example of USB 3.0 HUB slowing down when more than one device connected to it.
Are powered USB hubs better?
Because a powered hub uses mains power, it can give every device connected to it the maximum voltage that USB allows. So, not only can it run more devices than an unpowered hub, it can do so at full power, without any drops in performance.
