I've heard that CF cards have faster acess rate then most normal HDs, but I'm curious what moving the root directory (along with the boot loader, kernel and initrd images) will do to boot times. I'm presuming that the faster speed will help with initial decompression of the kernel, but beyond that I'm not sure.
Anyone have benchmarks of how long it takes to boot off a 4200 RPM laptop drive (or other HD) vs. a Cf card (same kernel and image config)?
I'll probably do some kernel hacking to get the boot times down, but if hardware I have laying around (256MB CF card + port on motherboard for CF) can make it boot even faster, that'd be great.
I don't think CF cards are faster than a hard drive. I believe their access times are around 25ms, whereas a hard drive is usually around 8-10ms.
Moving it to CF does not help your boot time significantly, even if CF access is faster than your HDD. Majority of boot time from the time the computer received power is BIOS and kernel decompression which initializes the devices. Then your distro sets up the system thru /etc/init.d. Unless you have a fast BIOS, what you can really do to save time is in the OS setup. Less processes = less time.
I may just use a CF for just shock protection, then.
