This strange issue still exists in 10.2: if Reduce Motion is DISabled (in Settings > General > Accessibility), then page loading in Safari often hangs for many seconds, as long as a minute. Not all sites are affected; this one certainly is. I have no idea what's going on, but the effect and solution are repeatable by simply toggling that one switch.
So, if slow load times are annoying you, check first that Reduce Motion is enabled.
