--- Comment #6 from Denis <denys.kostin at globallogic.com> ---
>I'm just curious why it takes a whole minute for this shader to initialize? This does seem like a bug. No one will wait for a whole minute to see the results - they will consider Linux broken.

hm, agree. I re-checked timings one more time, and found out that there was my
bad in calculation. I built mesa with debug flags.
New results (for release versions mesa):

18.3.5 (system) - 5.6 sec
19.1.0 (git-master release) - 5.5 sec

Before closing I would suggest to update mesa and re-check, whether you have
the same result with me or not.

In your case you can compile mesa manually, no need to make full system
upgrade.

btw - I am testing on fedora 29, it is shipping with 18.3.5
