Can somebody please explain status figures for load and DB - attached picture 1. what the lightning sign mean
2. Load number? - CPU is i5-7200U, dual core, 4 threads - and what number would be for 100% CPU load (all cores & threads)?
3. DB:X/Y - what numbers X and Y reflect?

100% load = 1.00 per CPU thread, so for yours that would be 4.00.

Yes, had in mind too (as htop show), until i've got figures well over 4 (5+).
I'm sure, as that was observed on different systems not only on one.
Could it be overclocking or kernel dealing with CPU states and speed?

I think that load is actually calculated as something like, "the number of processes requesting CPU time, or instructions in the queue, divided by the number of CPU threads," so load values greater than the amount of threads indicate that processes are having to wait for CPU time rather than being executed immediately - i.e. the system has too much to do (is overloaded) and may be slow to respond.

Thank you kitkat!

So I'll observe systems with that in mind and act accordingly.
