Site Health recommends a persistent object cache when your site crosses a size line, not when it is slow. Any one of seven counters is enough: a multisite network, more than 500 autoloaded options or 100,000 bytes of them, or 1,000 rows in the posts, comments, options, terms or users table. Revisions and media count as posts, so small sites trip it often. An object cache also needs a cache server, and a plugin alone cannot provide one. Decide first whether your traffic is the kind an object cache speeds up.
Server location and website speed are linked, but distance is only the fourth-largest term in page latency. Fiber physics caps the gain near ten milliseconds per thousand kilometers.

The best hosting for beginners is not the plan with the longest feature list. It is the plan whose decisions you can undo. Five choices lock you in, and only two are reversible for free.

Free SSL and domain management means a domain-validated certificate that renews itself, a DNS zone editor, and nameserver control. It does not mean wildcard coverage, a verified company name, WHOIS privacy, or a free domain.
