Google's AutoFDO & Propeller For The Linux Kernel Helps With Up To 5~10% Faster Performance
Google engineer Rong Xu has proposed adding AutoFDO and Propeller support to the mainline Linux kernel for its Clang-based build as it can help the system performance improve in the up to 5~10% range.
Google engineer Rong Xu has proposed adding AutoFDO and Propeller support to the mainline Linux kernel for its Clang-based build as it can help the system performance improve in the up to 5~10% range. These are compiler-based optimization techniques for generating faster binaries and Google has found combining AutoFDO and Propeller to be worthwhile for Linux kernel images. The selected microbenchmarks included Neper, a network subsystem benchmark, and UnixBench which is a comprehensive suite for assessing various kernel operations.
