I've dug deeply into LSF in the last few years and it's like a car crash - you can't look away. It feels like something that started in the early unix days but was developed into perhaps the late 90s, but in reality LSF was only started in the 90s (in academia). As far as I can tell development all but stopped when IBM acquired it some ten years ago.

Database locking can be a bit surprising at times. I recently stumbled over CREATE TABLE IF NOT EXISTS causing client timeouts - you might expect this to be near-instantaneous if the table exists, and it usually is, until it's not... because it always acquires an exclusive table lock, so it's blocked even by readers.

We run thousands of Linux desktop workstations from low-end workstations for developers to dual-socket machines with >1TB of memory at work. That's primarily because productivity for our use cases is so much higher with a Linux/Unix environment than Windows that it's not even remotely funny. However, almost all users still have either the standard corporate-issue Windows laptop, or a Windows VM on their workstation. Practically exclusively for Desktop Excel-based administrative tasks.

Generally speaking, the vast majority of our userbase likes their Linux workstations far better than their Windows machines, and that's after experiencing the significant downgrade to Gnome desktops due to Red Hat removing KDE.
