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.
Comment 2 Forgotten User ZhJd0F0L3x 2006-01-22 16:03:50 UTC 
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 ;)
