If I compare the performance of my Xperia X before and after SailfishX (official) flashing, I suspect it's no longer using the full power of its six-core cpu. Is there a way to check that?

Currently it does not. Antutu scores about 75k on Xperia X with Android 7.1 and about 45k on SailfishOS with Alien Dalvik.
EDIT: Of course it does not. Alien Dalvik runs Android 4.4.4 and therefore uses the Dalvik JIT runtime, while Android 7.1 uses the ART runtime with pre-compiled executables, hence the gain in speed.
I just realized that Alien Dalvik is, as the name says, Dalvik, while Android 7.1 runs ART. This is for sure the reason for the difference in performance.

I guess that is related to a known issue mentioned in the release notes:
Even though all CPU cores get eventually enabled, foreground apps do not always run on the big cores
In Alien Dalvik that may even be completely different story.

I notice that sometimes when the Xperia CPU Core 1 gets overloaded 100% persistent, it brings the entire phone to a crawl.
