cvs up has become very slow on arm64

A cvs up of /usr/src with the repository mounted over NFS has become very slow on arm64 (OverDrive 1000). Two runs: 38m22.67s real 0m08.83s user 0m29.80s system 36m42.89s real 0m08.27s user 0m24.29s system By comparison, an APU2 with the repository mounted from the same serv
