Hello
I made 5 attempts to boot for every different kernel tested, to have a reliable average speed on the boot time kernel, the Distro used is the new ROSA Fresh R3, I expected already cool results, the latest results are even better than those expected!
The times recorded are related to nr. 5 retries:
- kernel 3.10.34 - (default in ROSA Fresh R3)
- kernel 3.10.37 - (update that has had not the time enough for QA)
- kernel 3.13.11 - (the same version used for OpenMandriva 2014.0)
Here are some numbers, judge by yourself:
with R3 kernel boot times are almost halved, decreased by about nearly 5 second
- 10.1 secs with 3.10.34 (with R2)
- 5.7 secs with 3.10.37 (with R3)
- 5.5 secs with 3.13.11 (with R3)

The PC on which I have experimented these tests, it was rather old and with 80Gb HD is NOT fast!
