Mark Gavalda at Kinsta released some numbers from their in-depth performance benchmarks to see how different versions of PHP stack up against each other while running WordPress, Drupal, etc.
There’s a lot to unpack here, but something curious for most readers may be Kinsta’s discovery that in some instances WordPress 4.9.8 ran faster than WordPress 5.0.
Mark commented, “This doesn’t surprise us too much as the entire WordPress 5.0 project has been rushed. You can expect to see faster results with WordPress 5.0 as they continue to improve it.”
