What I see is sluggish UI behavior, for example dragging a window across the desktop, or hovering over a list. When dragging, the window lags way behind the cursor; when hovering it takes a perceptible amount of time for the item to highlight. Also benchmarks -- e.g. Blowfish gives a score around 38. This is after a fresh power-up boot.
It seems like someone, some process is holding interrupts disabled for too long a time.
But the good news is, that if I log off and back on, LL is delightfully quick and responsive with a Blowfish score around 16! This is very consistent, and I just discovered the log on/off sortof by accident.
I've been using htop and cpufreq-info looking for clues but no joy so far. Curiously when sluggish, Task Manager shows about 50% CPU usage (nothing else running) with Task Manager itself consuming most of that. When snappy, Task Manager shows only 4..5% CPU and again, Task Manager is responsible for most of that -- which seems most reasonable.
I submit this, wondering if anyone has similar experience, additional clues or a possible solution.
Thanks for listening.

If not looking for things, I'm waiting for things.
