Late 2011 MacBook Pro slow/laggy

My MacBook has been slow for years now, and it's really been irritating me lately that even just two safari tabs open with no other programs opened can get choppy and stutter. I don't think it was caused by updating to High Sierra or anything like that. I guess it could just be the hard drive or the ram amount, but I've used computers with 4gb of ram and an HDD before and they weren't near this slow to use for typical, common use case tasks like browsing the web. Maybe I should wipe the OS clean and start anew? Not sure, so any input is appreciated
