Hello Marek,

I hoped you would ask this...
...but first sorry for the delay of my announced numbers.
Our family is/was sick, my wife more than me and our children are fine, 
again.
So be lenient with me somewhat.

I think we can achieve this.

I'm running with LTO+PGO 'release' since late December (around 
Christmas).
My KDE Plasma5 (OpenGL 3.0) system/desktop was never agiler/fluider 
since then.
Even the numbers (glmark2) show it. The 'glmark2' numbers are the best 
I've ever seen on this system.
LTO offer only some small space reduction and hardly any speedup.
But LTO+PGO is GREAT.

First I compile with '-Db_lto=true -Db_pgo=generate'.

mkdir build
cd build
meson ../ --strip --buildtype release -Ddri-drivers= -Dplatforms=drm,x11 
-Dgallium-drivers=r600,radeonsi,swrast -Dvulkan-drivers=amd 
-Dgallium-nine=true -Dgallium-opencl=standalone -Dglvnd=true 
-Dgallium-va=true -Dgallium-xvmc=false -Dgallium-omx=disabled 
-Dgallium-xa=false -Db_lto=true -Db_pgo=generate

After that my 'build' dir looks like this:

drwxr-xr-x  8 dieter users    4096 13. Feb 04:34 .
drwxr-xr-x 14 dieter users    4096 13. Feb 04:33 ..
drwxr-xr-x  2 dieter users    4096 13. Feb 04:34 bin
-rw-r--r--  1 dieter users 4369873 13. Feb 04:34 build.ninja
-rw-r--r--  1 dieter users 4236719 13. Feb 04:34 compile_commands.json
drwxr-xr-x  2 dieter users    4096 13. Feb 04:34 include
drwxr-xr-x  2 dieter users    4096 13. Feb 04:34 meson-info
drwxr-xr-x  2 dieter users    4096 13. Feb 04:33 meson-logs
drwxr-xr-x  2 dieter users    4096 13. Feb 04:34 meson-private
drwxr-xr-x 14 dieter users    4096 13. Feb 04:34 src

time nice +19 ninja

Lasts ~15 minutes on my aging/'slow' Intel Xeon X3470 Nehalem, 4c/8t, 
2.93 GHz, 24 GB, Polaris 20.
Without LTO+PGO it is ~4-5 minutes. (AMD anyone?)

Then I remove all files/dirs except 'src'.

Next 'installing' the new built files under '/usr/local/' (mostly 
symlinked to /usr/lib64/).

Now run as much OpenGL/Vulkan progs as I can.
Normaly starting with glmark2 and vkmark.

Here comes my (whole) list:
Knights
Wireshark
K3b
Skanlite
Kdenlive
GIMP
Krita
FreeCAD
Blender 2.81x
digikam
K4DirStat
Discover
YaST
Do some 'movements'/work in/with every prog.
+
some LibreOffice work (OpenGL enabled)
one or two OpenGL games
and Vulkan games
+
run some WebGL stuff in my browsers (Konqi/FF).

After that I have the needed '*.gcda' files in 'src'.

Now second rebuild in 'src'.
Due to the deleted files/dirs I can do a second 'meson' config run in my 
current 'build' dir.

meson ../ --strip --buildtype release -Ddri-drivers= -Dplatforms=drm,x11 
-Dgallium-drivers=r600,radeonsi,swrast -Dvulkan-drivers=amd 
-Dgallium-nine=true -Dgallium-opencl=standalone -Dglvnd=true 
-Dgallium-va=true -Dgallium-xvmc=false -Dgallium-omx=disabled 
-Dgallium-xa=false -Db_lto=true -Db_pgo=use

After around 5-6 minutes (!!!) I can install the LTO+PGO 'release' build 
driver files and enjoy next level of OpenGL speed.
Vulkan do NOT show such GREAT improvements.

Only '-Db_lto=true -Db_pgo=generate' need ~3 times compilation and 
mostly linking time.

Below are some memory and speed numbers.
Should I send an additional post with a better title to the list?
Hope this helps ;-)))
