LPC: Booting Linux in five seconds

Parent article: LPC: Booting Linux in five seconds

While getting a lappie to boot in 5 seconds is quite an achievement, what I'd really like to see is my ThinkPad waking up from the suspend state almost instantaneously. Currently it takes about 8 seconds from opening the lid to a usable desktop.

Any chance of doing that?

What kernel are you running? I had slow wakeups on an X61 but it went away some time before 2.6.26.5.

How much RAM do you have and how fast is your disk? At best, 1GiB of Ram read at 60MiB per second will take 16ish seconds. If you manage some compression and only take the parts of memory used in running programs, you'll speed things up. But almost-instantaneous will be IO bound by your disk.

I assume he meant wake up from suspend-to-ram...
