Linux 4.19 Kernel Benchmarks On The Raspberry Pi
Written by Michael Larabel in Software on 13 March 2019. Page 3 of 3. 30 Comments

To some surprise, the Perl interpreter benchmark was slightly faster on both Raspberry Pi boards using the new 4.19-based kernel.

While a synthetic test, Stress-NG's context switching benchmark shows significantly lower performance on the Linux 4.19 kernel compared to the previous 4.14 release, though not entirely a surprise given all the security work and other hardening that's gone into the upstream kernel between these releases.

Stress-NG's message passing performance also points to a significant dip in performance on Linux 4.19.

But over the course of dozens of benchmarks run, the performance hasn't changed all that much. When looking at the geometric mean of all the benchmarks ran, Linux 4.19 was only coming in slightly lower than 4.14. All of the benchmarks carried out between Linux 4.14 and 4.19 on the Raspberry Pi 2 and Raspberry Pi 3 can be found on OpenBenchmarking.org.
