Recompiling The Ubuntu 20.04 Kernel To Speed Up Gameplay - You Couldn't Do This On Windows

00:02:06 Downloading the source files for the compilation process.
00:07:15 Applying a patch for some extra architecture specific speedups.
00:08:22 Editing the config file to remove some debugging.
00:10:20 Configuring the kernel to remove the slower parts of it.
00:35:30 Updating the changelog, so that the kernel version is unique.
00:38:10 Finally it is time to run the build process.
00:39:15 The build fails, so lets find out why.
00:48:35 The build fails again, lets see what the problem is this time.
00:52:45 The build is now successful.
00:53:30 Time to update GRUB so the kernel can be selected.
00:54:35 Time to install the kernel related debs.
00:56:10 Now I am setting up the benchmark results text file.
00:56:40 Time to download the benchmark files.
00:57:24 Now it is time to run the benchmarks.
01:05:50 Now the benchmarks are finished, so it is time to boot into the compiled kernel.
01:09:20 Time to run the benchmarks again on the compiled kernel.
01:14:40 Now it is time to compare the results

In this video I am recompiling the kernel in an Ubuntu installation, to see if I can get any kind of a speedup in a couple of game demos that I will be trying out. The beginning of the video shows how to go through the recompilation process and the ending part of the video shows the results that I managed to get after all of the time spent.
After removing all of these security and debugging options, it is like I have converted a wedding cake kernel into a pancake kernel, so lets see what difference it makes
