I'm also running on Java 1.8.0_25 64bit. And my Realms world is unplayable since 1.8. It got better with 1.8.1 but the lag still arrives after playing for 10 to 20 minutes in the same area of my world. Then you can't ride a horse or a minecart, place blocks or chat without severe hickups. And in the end you get kicked because of time out or other issues.
I'm using a map that was generated many version ago and uploaded to the Realms Server when 1.8 arrived. Maybe that's the reason for it? But then I don't understand why I can play without lag, if I wait for 10 to 15 minutes outside. If I log back in it seems fresh server resources were given to me and I can play a while without any problems at all... and I repeat, all in the same area. With a render distance of only 8 chunks. We are four players at maximum, but that does not make a difference. The lag comes no matter how many or few we are.
