For what it's worth, my 1.21.1.03 BDS has the same issue, but a perf recording during the issue period where a client is nether portaling mostly shows that the CPU "usage" is actually just threads spin-waiting on lock contention.
client-side-chunk-generation-enabled=true
for me, but it shouldn't matter greatly in this particular portaling event, the surrounding areas on both sides of the portal have been mutated and stored into the leveldb already so need to be fetched from the server anyways rather than the client generating its own.
The performance is extremely bad at all of the client view distances I tried from 24-50, and entering the nether portal takes 20-30 seconds.
edit: I spun up my world on Windows Server 2022 and it has the same issue, it's not exclusively a linux issue.
