So last night I hibernated my laptop and when I came in today it booted pretty close to instantly. I very seldomly hibernate my laptop because I frankly just don't see the same performance as after I boot cleanly from a full shutdown. But I got to thinking...
If you can get a reproducable test to show that its slower after resume from hibernate then file a BZ so this can be fixed. The possible cause is that after resume some of your apps/their data are still on swap so the first time you access them will be slower as they're paged in.
What if some/all services were able to be configured to "hibernate" during shutdown, then at single program or service called by rhgb brought these programs back to life? I think it would be helpful to reduce the number of services that start during boot for my laptop (httpd, mysqld, vsftpd, etc.). Is such a feat possible? Could there even be a decrease in boot time?
This is just re-inventing hibernate again with even more work which is not a good use of developer time as compared to fixing any bugs which actaully exist in hibernate/resume.
