Description Andreas Jaeger 2006-01-22 15:10:39 UTC

I have the subjective feeling that the saving/loading of pages is much slower with Beta1 than it was with 10.0.  Even the kotd from Alpha4 seemed faster.

I can now read the numbers (7% done etc) easily, before they went faster.

Stefan, can you reproduce this with some objective numbers?

it's not a bug - its a feature.

Now always a ~500mb image is saved which makes your machine much more responsive after resume.

If you want the old behaviour back, do
echo 0 > /sys/power/image_size

Yes, i'll do some magic configuration variable for this in powersave, but not before beta3.

I'll leave this open although the bug is clearly INVALID to remind me of the powersave bits.

Comment 3 Forgotten User ZhJd0F0L3x 2006-02-02 20:27:17 UTC

we can now set the image size in the config file (SUSPEND2DISK_IMAGE_SIZE), i still have to implement the automatic retry in case of "not enough swap".

Comment 4 Forgotten User ZhJd0F0L3x 2006-02-13 18:04:46 UTC

automatic retry is also implemented, but hard to test. Let's see what testing brings ;)
