I have the same problem, but it loads slowly as soon as I install WordPress, I don't think it's related to the plugins.
Is there a way to improve WordPress performance?
Writing posts or adding products to WooCommerce take forever. Then the site throws 403 errors forcing a page refresh. Not good UX and Im sure end users will just walk away.
I've hosted in IIS for 20+ years and don't intend on moving *nix for one site (If that's the only solution).
