Follow-up Comment #2, bug #18502 (project hurd):
OK, I built gnumach with the following in model_dep.c:
set_cr0((get_cr0() | CR0_PG | CR0_WP) & ~(CR0_CD | CR0_NW));
And I got worse performance:
0m0.040s 0m0.130s
0m0.000s 0m0.000s
Booted back to normal gnumach:
0m0.010s 0m0.020s
0m0.000s 0m0.000s
That is just from running times on a little C program that counts to
1000000000, so it's obviously not scientific.
