Question 2

H2O or Nginx: which is better for high-traffic websites?

Accepted Answer

H2O often benchmarks faster for static content and modern protocols like HTTP/2, but Nginx has a more mature ecosystem and broader community support. Choose H2O for raw performance, Nginx for extensive features.

Question 3

Does H2O support WebSockets?

Accepted Answer

Link against H2O as a library and use its API to initialize and run the server within your code. The documentation includes examples for custom integration, but it demands C expertise.

Question 5

Is H2O good for serving PHP applications?

Accepted Answer

H2O can serve PHP via FastCGI or proxy setups, but it lacks built-in PHP modules, requiring extra configuration. It's optimized for performance but may need more effort for dynamic content.
