My HP laptop is not the newest and often seems to run slowly. A few minutes to boot up and sign in and get the browser going.
Even typing this message, sometimes the characters don't appear instantly.
So I ran the winsat mem test, you can see it below. What do the two warning messages mean?

C:\Users\Owner>winsat mem
Windows System Assessment Tool
> Running: Feature ENUMERATION ''
> Run Time 00:00:00.00
> Running: System memory performance assessment ''
Warning: The RDTSC to QPC delta is too high ( CPU 1 )

Apparently the max memory for this HP is: 8192MB, 2 slots.

I ALSO attach two screenshots of the Computer management performance manager system summary, the task manager, and the resource manager, taken a minute apart to get the two parts of the system summary.

How to tell if I need more memory

If the problem is memory related you would see the amount of used physical memory become close to 100% and the number of hard faults/sec would increase noticeably when the system is slowing down. From your screenshots this does not appear to be the case.
