@MojangSupport I have recently started a free trial on a realm, and it gets VERY laggy, i think that it's because there is more than 1 player online. My friend had a realm and it barely got laggy even when there was 5 people online at the same time. Please help me.

Oh no, let's take a look to get you into your game! First, can you let me know what system you're trying to play your Realm on? Also, have you tried any troubleshooting at all? ^BT

I am playing on java edition. And i tried typing /reload and also closing and opening the realm but nothing helped.

It could be due to many things when lag is at play. Could be your firewall/antivirus or overlays that you may have up wihtout knowing it. Try restarting your computer and then going into the Realm to see if things run a bit smoother. ^TK

Thank you for answering! But I use Mac
