Could be you are not having lots of background processes, daemons and so on running? I am always having > 200 MB swap in use. Maybe for a lesser amount compcache is working?

Then it is normal, that a few MBs are used within eMMC swap, as swapset enables compcache at a later time.
Could be done a bit earlier.

I am currently using two smaller eMMC swaps instead of a big one, and it feels more laggy but with shorter lags. It is really hard to tell if there are differences without a test suite and with so many use cases.

Now I understand.
No, as freemangordon stated in some earlier post. There is no control when/where/which swap is used, if compcache is enabled.
