The first time I tried Ubuntu it was in a virtual machine within Windows XP. There were many good things, but the really surprising thing is that one system within another was faster than the native one (in this case XP). When I installed Ubuntu as a native, how could it be otherwise, everything was still more fluid. In addition, this year I have released a laptop with which I can not even blink how fast it starts. For all this, I was surprised to learn that Ubuntu 19.10 Eoan Ermine will boot even faster if it fits.
The Ubuntu kernel team has decided change kernel image compression to LZ4 and the first version to enjoy this novelty will be the Eoan Ermine that will be released on October 17. They made the decision after evaluating the different compression options and will use the LZ4 on the supported architectures for kernel images and initframs. Ultimately, starting with the next version, Ubuntu will boot up faster than ever.
Ubuntu 19.10 will boot faster than ever
Colin Ian King he explains So:
In compression size, GZIP produces the smallest compressed core size, followed by LZO (~ 16% larger) and LZ4 (~ 25% larger). With decompression time, LZ4 is more than 7 times faster than GZIP, and LZO is ~ 1.25 times faster than GZIP on x86… Even with slow spinning media and slow CPU, the longer LZ4 kernel load time far exceeds the tfaster decompression ime. As media gets faster, the load time difference between GZIP, LZ4 and LZO decreases and decompression time becomes the dominant speed factor with LZ4 as the clear winner..
Perhaps, talking about a 7 times faster startup based on the difference when decompressing is saying a lot, but it is a fact that Ubuntu 19.10 will start much faster than Disco Dingo and previous versions. If I'm not mistaken, we can check it at the latest on September 26, when Canonical launches the first beta by Eoan Ermine.
Are you saying that the boot image will now be 25% larger? horrible, my 4-track album is already fully saturated….
If I have ubuntu 19.04 will I have to reinstall the distro for that compression, or is it enough to update?
