Hi folks,
there are some ideas for future sppedup of cdk box I had in queue,
want to give them out now in expectation that someone on developer side
can engage more.
1) Grub delay
Grub has 5 seconds timeout in CDK. We can probably change to 1 or even 0.
2) Initrd delay
Roughly 4 seconds, probably not worth the optimization in first round.
2) Starting services
Probably starting bunch of services which are not needed.
By far longest one is kdump.
- quickly tried systemd-analyze on CDK after first boot:
- biggest thing - kdump took ~ 25seconds and system is waiting for it
do we need it in cdk box by default?
- probably bunch of small things for no reason, like
wpa supplicant service - no wifi in cdk
- we could investigate possibilities of
systemd-readahead-collect and systemd-readahead-replay
(although probably not so useful in vm)
Hope this helps,
David
David,
Thanks for these ideas about CDK performance improvements. We definitely
should work on these.
