Optimise usage on slow usb pen drives

[Ygarr]

Is there some options(e.g. for GRUB) to use OS more in RAM, copy to RAM, with less usage disk access writing? Or even option to sync manually to write changes to disk?

Hi there,

you can completely disable the USB persistence partition with this GRUB option: kiwi_hybridpersistent=no

I also found this for creating a RAM disk, please report back whether it works for you: rd.kiwi.ramdisk ramdisk_size=2048000

Seems no effect.(with the exception of disabling persistent, it works definitely ) Also tried in sysctl.conf vm.swappiness = 0 vm.dirty_background_ratio = 20 vm.dirty_expire_centisecs = 0 vm.dirty_ratio = 80 vm.dirty_writeback_centisecs = 6000. At least nothing became worse

Hmm, at least disabling the persistence partition should definitely work. Please try removing rd.live.overlay.persistent from the default GRUB options.

I'm also confident that disabling persistent will help as well. But this is an extreme case, if you understand
