Ram and Hibernate

Is it linear?

will double the ram take twice as long?

got 256 and thinking if i should go 512 or 1gb.

It's pretty close to linear, yeah. Figure the hibernation process basically writes the entire contents of RAM to the HDD. Logically, the write process would double if you doubled your RAM or quadruple if you quadrupled your RAM.

I run 512MB and both hibernate and resume are pretty quick with a 7200rpm desktop HDD, a matter of a few seconds.
I'm also running older hardware than you, as well.

It's only linear during the loading bar section during resume (that's when the hard drive is being dumped back to ram), so you might double that time.

But your POST and the time it takes from the finish of the loading bar to when you are actually up and running is still the same. So overall when you sum up all the times, there wont necessarily be a linear correlation in overall resume time as a function of ram size.

Thanks thought it would be linear, but thought there was a chance it coulda be due to the hard drive having to take the time to find a place to write.

right now im at like 2-3 going into, 12secs sounds like a long time if i went a gig.

when i last time opened my system, i upgraded from 512MB to 1G, and i think the times of wake up from / go to hibernation is nearly the same... i think windows dumps only the used megabytes, not the whole, so if the system is not fully loaded, there will be no huge difference...
