Linux 3.5 To Linux 4.5-rc1 Kernel Benchmarks

Written by Michael Larabel in Software on 25 January 2016 at 11:10 AM EST. Page 3 of 3. 4 Comments.

With the CPU-based TTSIOD renderer is one of the few tests on this Xeon Haswell system where the Linux 4.5 kernel performance went up compared to Linux 4.4. With Linux 4.5, the performance is now back up to where it was running on Linux 3.16 and prior.

Most other results aren't too exciting.

With the rest of the benchmark results not being too exciting, if you want to dig through the rest of the data you can find all of these Linux kernel benchmark results via Over on continue to be daily automated Ubuntu/Fedora kernel benchmarks and other specialized Linux 4.5 testing articles will be published on Phoronix in the days ahead. The good news at least is that for this particular system and the workloads tested, there were no regressions spotted and that the Linux 4.5 kernel performance is looking in line with the solid Linux 4.4 kernel. If you haven't yet read about the new functionality for this next kernel release, see our Linux 4.5 kernel overview.
