Hi<p>Document Length is much bigger with WP. Is it compression being off in Apache/PHP or caching in React?<p>Update: ok, compression is off in Apache. Hmm, I'm not sure ab is a good benchmark tool here. Your React combo is asynchronously pulling data while WP is mostly synchronous. To be fair, you need to check "full loading" times.<p>WPT Apache: <a href="http://www.webpagetest.org/result/151027_GJ_d747f0a207fa4b72af35d63f53dfd447/" rel="nofollow">http://www.webpagetest.org/result/151027_GJ_d747f0a207fa4b72...</a><p>WTP React+: <a href="http://www.webpagetest.org/result/151027_83_f3b299e3ab7957a473bb1cd29a2f12eb/" rel="nofollow">http://www.webpagetest.org/result/151027_83_f3b299e3ab7957a4...</a><p>Fully Load for Apache is: 3.0xs<p>Fully Load for React+ is: 3.7xs<p>I can also see that you haven't done basic optimization on Apache (KeepAlive off, compression off, MaxClients, etc).
