RadeonSI's Mesa Shader Cache Can Be A Big Help To Modern Linux Games

Since it doesn't matter about keeping the cache across reboots, right?

It does matter, it is disk cache as point is to keep cache there . Otherwise you will lose it and first app run will be again caching procedure so slow.

Whatever, it is optional so do it how you like but driver even beside this disk cache already do cache in ram, so what you trying to do really has no point

It seems that with Mesa 17.1 I finally can start the Trine trilogy on PC without a all time load up time of 5-10 minutes (no joke)

Great article, Michael.
It's not often you see unambiguously null to positive results for new features.

This is great to see further confirmation of the performance (FPS and load times) improvements from this feature.

there is no fps improvements from this feature. it is seen on benchmark only because benchmark is short and restarts game. if you don't restart game, you will see no fps improvements during play after first shader loads.
if you want to see fps improvements, you should pay attention to this:

Shader cache should also reduce hitching/stuttering. Might be worth investigating this with frametimes since also the opposite can occur when it doesn't work right.

Great article Michael and congratulations to Timothy Arceri for the awesome work.

Those are some very encouraging results. Decreased load times for a few titles, higher fps for a few titles, and no discernible penalty on any.

Phoronix: RadeonSI's Mesa Shader Cache Can Be A Big Help To Modern Linux Games

With the rest of the RadeonSI shader cache support landing in Mesa, I have carried out some benchmarks to measure the impact of this on-disk GLSL shader cache not only for the performance of games but also the reduced load-times.
