That's pretty good. My bandwidth is typically 105 download and about 25 upload. It used to be that upload was capped at 10 Mbps for cable (You can thank google fiber for this.) I guess they opened it up a bit in the past 3-5 years.
Don't worry about bandwidth. It's hard to chew up 41 Mbps, unless you're downloading torrents and watching netflix on multiple machines. You should hardwire to your modem about once a month to ensure you aren't getting shortchanged on your promised speeds. Remember when you get a package, your bandwidth isn't ever supposed to drop below that number. If it does, call the company and get it fixed.
