:-)
You should not compare a playing program with Chest.
They perform quite different jobs, even when the result from both
is a mate PV.

That is, because another job with 350 MB is still running all the time.
[The mate in 17 twin.  My first guess of 8 hours turns out to be too small:
 it is at 32 hours, now, and will need 1-2 days more...  just another guess]
There is still enough memory left to add another 60MB Chest running,
but not much more (I tried 120MB, and the system started to page as mad).

Yeah, paging/swapping is to be avoided.
