Hello, I just tested NetBSD 7.0_RC1, and it seems that 7.0 is *very* slow to boot compared to 6.1.5. The problem seems to be entirely in the userland because 7.0 kernel with 6.1.5 userland is just as fast as 6.1.5 kernel. And based on vmstat -s fork numbers right after boot, the problem is likely just in the rc system.
Just for the record, I did the tests on a qemu sparc emulator with no other configuration than rc_configured=YES: 6.1.5 boots in 11 seconds (with 6.1.5 and 7.0 kernels), 7.0_RC1 takes 45 seconds. A few vmstat -s numbers after boot: userland+kernel 6.1.5: 55483 total faults taken 28643 traps 5072 CPU context switches 60741 system calls 285 forks 9765 anon page faults 11357 object faults 13705 total name lookups 11417 good hits 1947 miss userland+kernel 7.0_RC1: 288771 total faults taken 147872 traps 11634 CPU context switches 159367 system calls 1064 forks 30715 anon page faults 63240 object faults 34700 total name lookups 31061 good hits 2108 miss I also tested 7.99.19, and it is just as slow to boot as 7.0_RC1, and vmstat numbers are pretty much the same. In the not very scientific qemu boot time test -current kernel is also unfortunately slightly slower to boot 6.1.5 userland than 6.1.5 or 7.0 kernel. Arto
