Is there a difference in boot mode of OpenBSD and #FuguIta? I have a Dell PC where OpenBSD is very slow without disabling acpimadt whereas #FuguIta has no such problems.
Any guidance will be gratefully received.

scanning partitions: cd0a sd0i sd0j FuguIta's operating device(s): cd0a sd0i Which is FuguIta's operating device? [default: cd0a] -> sd0i # in case that sd0 is internal disk
If FuguIta runs slow as OpenBSD with this procedure, the problem could lay on internal disk device. -- kaw 2020-07-21 (Tue) 16:28:11
and one other escaping attention now.
To this end, I started reading through the show and list variables in the UKC config and found that #FuguIta has a lot more that get initialized than vanilla OpenBSD. When that did not work out, I once again disabled acpimadt, installed the operating system and waited for it to boot. The scenario now stood at reordering libraries (library_aslr). I let it complete the first time and then disabled the service via rcctl. This made a dramatic impact on reboot.
Presently, after having run sysupgrade (following -current), the performance is acceptable as good as on a ThinkPad.
My speculation is to do with the execute bit. I haven't read the source code to be certain of this but would appreciate your knowledgeable thoughts on it. I will try the above solution if video and browser performance in unacceptable with my continued testing. -- Fugu 2020-07-21 (Tue) 19:37:36
