Ubuntu 20.04 LTS A Nice Upgrade For AMD Ryzen Owners From 18.04 LTS
There were a few regressions spotted along the way.
Due to the newer compiler, you can expect compile times to be longer due to more optimization passes, etc. But some of the slowdowns in compile times were a bit surprising especially in relation to 19.10.
But overall in moving from 18.04 to 20.04 should yield some nice improvements especially with newer systems like the AMD Ryzen 3000 series.
