I'm using this day off to do my host OS updates a bit early. Main focus is looking at the CCache perf on my Gentoo desktop system.
This is now my second update cycle using CCache with Gentoo, and at least right now I'm not too impressed. Hit rates are hovering somewhere around 10%. Packages like LLVM or Clang, which were build both last time and this time, were not sped up at all.
And yet...I'm now sitting here considering how hard it would be to write a librados CCache backend. 🤦
