For each install using pacman
or yay
it takes about 1 min 40 secs to complete the install, and the main time is taken by this mkinitcpio and grub update after every transaction
.
Here is a gif to see that in action.
My experience.
The DL time 12 sec.
Reading/Enter ~ 5 sec.
All together 1min.1Sec.
Seems normal for me, but ...

All together you have 1:37 min.
It takes the longest to build the fallback.img
But we know nothing about your system (inxi -Fxxxza),
do you use HDD or SSD or Nvme?
For more feedback I change the
Headline: Why is this happening?
New: Why does it take so long to build fallback.img?
- You can disable the creation of a fallback image by removing "fallback" from the preset file in
/etc/mkinitcpio.d/
- You can change the compression algorithm to e.g. LZ4 in
/etc/mkinitcpio.conf
Ahh, no (ups, gzip) is compression used
# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"
# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()
With kernel 5.9 you'll get ZSTD as an additional option
Cool, with lz4 it need 35 sec. instead 1 min.
35 seconds?
mkinitcpio -P
(regenerate all) takes about 10 seconds here with 3 kernels and a combination of ZSTD and LZ4, and I can get that down even more if I used the default compression settings.
(fallback is only generated for default linux
though).
All together to my last test in post above
What do I do with the gained time, I send my beloved a nice email
I know, all that effort to save some extra seconds in life. What could you possibly do with all that extra time.
OT
I became a chain smoker in the waiting time until a 256 KB disk was written (no smoker since 2011).
But today, boot time over 10 sec. is a no-go
Ahhhm... I'm old school, and boot ttime etc etc is all relevant. Compared to the old days we have nothing to complain about. Booting in the old days took forever, so complaints about boot time these days rather crack me up. But then I started on computers using punch cards.
Well the 1980s home computers didn't really have boot time at all, you turned it on and the BASIC prompt appeared after one second
That's right, those were the tube TVs that had a start-up time .
It should be only illustration of time (feeling), not a direct comparison.
If we go on like this we will get into trouble with the "falconer" because of the OT.
Not the big one the small ein mean
Takes me close to a minute with 1! kernel
The advantages of having a more recent/better CPU are tempting
/ot
Well this is only a dual-core mobile Kaby Lake, not very powerful at all
I would simply disable the fallback image creation, gives you a nice speed up.
