Do USB extenders degrade performance?

post #1 of 6
Thread Starter 
The way my new setup is set up, my keyboard and mice are a few feet short of reaching my computer. I was wondering if USB extenders, or plugging them into the monitor USB slots instead of the motherboard itself actually degrades performance (for example, a few ms lag). Is this true?

Few ms? Nah. Maybe if monitor has crappy hub, but not from an extender. Electricity travels pretty dang fast.

Extenders won't cause any lag, however, plugging it into the monitor could as they usually have USB hubs which add slightly to the signal time. I know when I had my mouse in my monitor I could feel that it was slightly sluggish, using extenders now and no such problems!

I dont believe any short extender is going to make a noticeable or measurable difference.

My Bluetooth receiver is run through a ~9" USB extension, and nothing lags that I can see in normal use.

Actually electricity is slow... it moves at around 84mm per hour, or 3.3 inches per hour...
But in all honesty, I run probably 12' of extenders for both my keyboard and mouse, and I notice no lag, then again I'm not paying much attention, but there isn't much, if any.
