I am running latest high Sierra on 2015 rMBP 13 inch, i5, 8 gb ram. Recently started using safari because I love a lot of the gestures and a lot of nice integration with iOS and because safari is the default browser on my iPhone. Also for me force touch on trackpad to sneak peek links is a game changer, especially browsing reddit. I can just peak at a pic or link without having to go to another page and go back to the feed. But Jesus safari is SOOOOO much slower on many sites than chrome, especially on youtube an reddit and many other sites I frequent. If I open up safari and click youtube or reddit, it will just hang there with the blue loading status bar on the URL in safari for a good 3-4 sometimes even 5, before it loads, and then loading is very fast after this hiccup. Funny thing is safari starts loading macrumors and a few other sites fine but a hand full like youtube and reddit have this issue...Safari is responsive its not frozen, its just stuck on the "waiting for.." stage for so long. If I try the same sites in Firefox or chrome they start loading almost instantly after I hit enter or click the bookmark. I really love safari and Im trying to get used to it but its painful to use with these issues. anyone else figured something out?
