I agree with Richard. Wireshark does use multiple threads, in particular for file status, but the important bit (UI, decode and analysis) all runs on a single thread.

While WireShark runs on multi-core CPUs, it does not distribute the important work, AFAIK, among separate cores.
In my experience, the things that improve Wireshark performance are:
1. Memory. 64GB or more.
2. Using SSDs or NVMe.
