Ubuntu Praises 5~7% PGO Compiler Optimization Performance Benefits
Over the past year we have seen Canonical engineers focus more on optimizing the performance potential of Ubuntu Linux
Sergio Durigan Junior has recently been exploring PGO optimizations for RISC-V while using QEMU emulation and running from AMD Ryzen hardware. Nonetheless, as we have seen above, Profile-Guided Optimization is a great technique when it comes to increasing the performance of a software, and we hope that this blog post and our documentation can paint a better picture of how you can implement it in your stack." So while Canonical/Ubuntu have no plans for using PGO at scale for being able to optimize all Ubuntu packages given the dependence on profiles, this more narrowed exploration of speeding up their RISC-V package compilation with x86_64 build farm is showing some very beneficial 5~7% performance improvements thanks to Profile Guided Optimizations.About The AuthorMichael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
