Also, must we expose Vpdumper_hash_tables to Lisp? Surely it'd be better to keep it private to pdumper.c.
I'll CC: to Daniel to see whether he has any insights about improvements in this area.
PS. I ran that benchmark on my home desktop, an Intel Xeon E3-1225 v2 running Ubunto 18.04.2. To run it, I rebased your patch and also removed the no-longer-used PDUMPER_CHECK_REHASHING macro that my GCC complained about (wonder why that didn't happen for you?), resulting in the attached patch against current master 8ff09154a29a1151afb2902267ca35f89ebda73c.
