SEO definitely puts a lot of pressure on people. Most guides these days talk about performance, and performance is directly linked with services such as CDN's.

But like you say, this can definitely be resolved through Web Servers and resource optimisation.

For WordPress blogs, OpenLiteSpeed has been a godsend to run a WP blog with up to par performance.

Yeah, I know. I've developed with/for WordPress for 10 years and most performance issues can easily be mitigated by optimizing your resources, using caching and more. I never had to rely on CDNs for good performance, though, also SEO agencies try to sell you this. Hard to explain to customers, though.
