Heap max 4269.6MB

Good afternoon everyone.
 

I have a server with a few mods and many times when there are 6 or 7 people playing and it's horde night there is quite a bit of lag.
I realized that there are values on the server that reach their maximum and that is what causes lag to exist.

2022-09-02T20:03:46 83042.226 INF Time: 1374.59m FPS: 39.93 Heap: 3927.7MB Max: 4269.6MB Chunks: 997 CGO: 93 Ply: 4 Zom: 6 Ent: 11 (293) Items: 2 CO: 5 RSS: 6070.0MB

When the value Heap: 3927.7MB is equal to Max: 4269.6MB the server starts lagging. I would like to know if the heap value can be increased manually.

server specifications
windows server 2019
Dell PowerEdge R720 Server 2 x E5-2690 16 Cores, 192GB Ram a 500GB Samsun EVO 970 SSD

Any other information you need I can provide.

Thank you very much for any help you can give me.
