critical

minecraft is using 1039% of server-thread time.

Of the server-thread time this profile sampled, 1039% sits inside minecraft. Check its config for the expensive features first, update it, and if the cost stays where it is, take it out and profile again to confirm it was the cause.

warning

TPS is 17.9 against a target of 20.

The server is completing 17.9 ticks a second where it should manage 20. Everything timed in ticks slows with it: crop growth, furnaces, mob AI and redstone. On Fabric the standard fix is Lithium for the tick loop, FerriteCore for memory, and C2ME if chunk generation is the cost.

warning

Garbage collection is running every 22683s, averaging 875.3ms.

The G1 Young Generation collector is running every 22683s and averaging 875.3ms. Each pause is a tick the server does not get. If the heap is also near full, fix that first. If it is not, tuned G1 flags are the usual answer: search for an Aikar flags generator and use the output for your heap size.
