Web server choice strongly affects site speed.
Apache
Oldest, very flexible. But slower than modern alternatives.
Nginx
Fast, low resource use. Ideal for static content and reverse proxy.
LiteSpeed
Fully Apache-compatible, but 2-3× faster. Pairs with LSCache to supercharge WordPress.
Which to pick
WordPress — LiteSpeed. Static/API — Nginx. Legacy — Apache is fine.
On Sayt.uz
Plesk hosting uses Nginx+Apache hybrid. LiteSpeed is offered as a separate plan.
