CentOS 6 Through CentOS 8 Benchmarks On Intel Xeon Server

When running multiple SQLite operations in parallel, there is a big speed-up going from CentOS 6 to CentOS 7 while from CentOS 7 to the new CentOS 8 is only a minor improvement in performance. Going from CentOS 6 to CentOS 7 out-of-the-box means transitioning from EXT4 to XFS (just as upstream RHEL 7 did) as well as going from the CFQ I/O scheduler to MQ-DEADLINE for this SATA 3.0 solid-state drive. With CentOS 8 / RHEL8, MQ-DEADLINE is the default scheduler for non-NVMe drives. Disabling Spectre, Meltdown, and friends does continue to provide a speed improvement for workloads like SQLite.

And a look with the similar SQLite Speedtest.

The t-test1 memory allocation benchmark continued improving nicely in performance with each CentOS/RHEL release.

Workloads like Rodinia also improved significantly with time thanks to the newer GNU Compiler Collection and other improvements.

Even Perl performance continues evolving nicely.
