This actually creates more problems because when turned on it slows down this blog when using the Scalia theme:
When “Load CSS Asynchronously” is turned off the page is rated a B instead of a C. (This is the case with Voxco theme with Litespeed Cache without Cloudflare, with Cloudflare this combination the rating seems to stay the same. With the Scalia theme without Cloudflare similar negative effect of altering Litespeed in this way but ustilizing Cloudflare as well it goes from a B to an A). Cloudflare itself has no influence except for minification. See here
