RHEL 8.0 is faster than RHEL 7.6 for the basic SQLite benchmark to get things started, but Ubuntu and Clear Linux on EXT4 are much faster in this particular test. Keep in mind most servers aren't running SQLite, however.

A better I/O workload for servers is BlogBench that models the workload of running a web blog server. RHEL8 was the fastest of the distributions with the read performance on both servers but for the write performance the RHEL-based distributions fell noticeably behind Ubuntu and Clear Linux.

The NAMD performance was effectively flat across the Linux distributions tested.

HMMer's speed improved nicely on RHEL8 compared to RHEL7 but the Ubuntu performance was an outlier for being noticeably slower than the rest.

With the MAFFT scientific workload, Ubuntu again was the slowest while RHEL8 regressed ever so slightly compared to RHEL 7.6 while Clear Linux was the fastest.

Clear Linux also was the fastest with GMPbench.
