**Boot mode difference [#cd61aa39]
>[[Fugu]] (2020-07-19 (Sun) 15:51:32)~
Hello Kaw:~
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.~
Thank you.~

-The kernel config of #FuguIta is almost same as GENERIC.~
Differences are as follows:

So I don't know why it behaves differently.~
Since the storage device used is different between regular OpenBSD(internal HDD, SSD...) and FuguIta(DVD, USB Flashdrive, SD card...) there may be something wrong with the built-in disk device.~
In any case, I think we need to see what's slowing down regular OpenBSD.
--disk I/O
--stray interrupts
--anything else?

- Thank you for the detailed response.  It has to do with buggy bios - APIC.  Thank you for sharing #FuguIta with us. -- [[Fugu?]] &new{2020-07-21 (Tue) 09:49:27};
- With following procedure, you can check whether the internal disk or its corresponding BIOS function causes the problem:~
-- In internal disk, make a directory named "ISO" at the root of a partition which is FAT, NTFS, Linux ExtFS or OpenBSD FFS.
-- Put a FuguIta's ungziped ISO image into "ISO" directory.
-- Boot FuguIta with LiveDVD or LiveUSB.
-- The internal disk will be listed as follows:
 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
-- Select internal device, then continue booting. 

>If FuguIta runs slow as OpenBSD with this procedure, the problem could lay on internal disk device. -- [[kaw]] &new{2020-07-21 (Tue) 16:28:11};

- I had quite a few ideas to test this:~
--Chroot install
--chain load from a different OS
--install via different system and move hard drive
--use a different boot manager
--install #Fuguita and hack via ramdisk

>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]] &new{2020-07-21 (Tue) 19:37:36};

- Summary Update:  During upgrade/install, the acpimadt needs to be disabled during runtime only.  All things work except for the cpu temperature which is stuck at a very high inordinate value.  The only similarity found is when the install medium is flash disk.  Fans, hibernate, sleep - power management; userland setup; networking have no problems.  Interestingly, #FuguIta also spends some time in kernel reordering but being a ram-mounted filesystem, the time spent is comparatively smaller.  This is a two-hard drive machine and OpenBSD live USB is now getting stuck before Install/Upgrade/Interrupt message prompt (custom part of #FuguIta) - seems to be directly correlational to number of partitions.  Pressing power option still gives back the prompt.  Although the device will not be high workload intensive, lack of temperature monitoring (#FuguIta live also lists the same numbers) is unnerving. -- [[Fugu]] &new{2020-07-22 (Wed) 14:55:26};
- Thank you for the detailed information.&br;Is vanilla OpenBSD slowing down because the CPU temperature is considered high and the CPU clock frequency is low?&br;If let apmd enabled and manually change the CPU clock with the apm command, can you see anything relevant? -- [[kaw]] &new{2020-07-23 (Thu) 12:54:58};
