For whatever it’s worth, operational database systems (many users/connections, unpredictable access patterns) are beneficiaries of modern hyperthreading.
I’m familiar with one such system where the throughput benefit is ~15%, which is a big deal for a BIOS flag.
IBM’s POWER would have been discontinued a decade ago were it not for transactional database systems, and that architecture is heavily invested in SMT, up to 8-way(!)
