Here are some timings for Isabelle/3e84f4e9651a on Pi OS 64bit beta (Debian 10.6):

Finished Pure (0:07:01 elapsed time, 0:07:01 cpu time, factor 1.00)
Finished HOL (3:04:18 elapsed time, 8:52:18 cpu time, factor 2.89)
Finished HOL-Word (0:28:07 elapsed time, 1:33:39 cpu time, factor 3.33)
Finished HOLCF (0:11:18 elapsed time, 0:26:53 cpu time, factor 2.38)

It is good to see that our huge HOL image already works on this tiny machine,
with interpreted Poly/ML.

HOL-Analysis and HOL-Library failed, due some to odd timeouts and missing z3
for arm64-linux.
