Poor performance when generating a lot of chunks

When a player is generating a lot of chunks very fast (tested using elytra + rockets), the server lags a lot and the console gets spammed with Can't keep up! Is the server overloaded? and moved too quickly!

This isn't enough information for me. What you describe can also be observed in vanilla. If you want to report performance issues, please run a profiler (eg. spark) and post the result here.

Thanks. Please make sure noTickViewDistance in c2me config is disabled. If you can still replicate the behaviour, please share the c2me and antixray config, so I can try to reproduce this.

Thanks. Please make sure noTickViewDistance in c2me config is disabled. If you can still replicate the behaviour, please share the c2me and antixray config, so I can try to reproduce this.

Yes, noTickViewDistance is disabled. I'm using default config for both.

noTickViewDistance is set to some compatability mode by default. I don't yet know why that increases the load of antixray so much, but disabling noTickViewDistance by setting enabled to false, seems to resolve that.

Oh, I thought noTickViewDistance was disabled by default. I disabled it and now the TPS are fine when generating new chunks. I'll use 1.18 simulation distance instead.
