We have performed benchmarking PXC 8.0.34 on RHEL, Ubuntu, and Debian. Debian and Jammy performed better than RHEL.
Are there any parameters that needs to be tuned in PXC specific to RHEL?
Can you give more info here? What versions of each? What kernel version was each using? Did the hardware match exactly on each? What packages were installed on each that were not installed on the others? There’s many variables at play here. At a high-level, I’ve never heard of needing to tune ‘RHEL’ in any specific way.
