Minecraft Anti X-ray Plugin?

Hi, I'm looking for a Minecraft Anti X-Ray plugin for my server. Spigot has an anti-X-ray plugin which works well, but it still takes a lot of RAM and so it lags a lot. Does anyone know of an alternative to the Spigot Anti X-ray plug-in that does not have a lot of power?

Unfortunately there are no good alternatives…

All other plugins check how much ore you have mined… Can also be triggered as a normal player, and xRay is not blocked with it.

Which host do you use?

I have never had any problems with the Anti xRay function

I host at prepaid-host.de. Have 16 GB on the root server there. At first it only had 10 GB on the server, which was stupid, but we were with 15 players who were tpt to a middle and there the anti xray flagged blatantly

So it's definitely not due to the RAM.

If you switch the function off, will it work again, or how do you come to the conclusion that the Anti xRay is the problem?
