timing - How I can receive page summary by using Java? -


i want receive next info web page:

  • ttfb
  • page load time
  • resources (css, js, img ...) load time

required condition: info must received in 1 request. have solution of problem on java?

ttfb: open socket server. gives network latency + socket opening time. via socket should send http request. moment when http header - ttfb... but... said - contains network latency, can redirect response, or protocol upgrade or wte. should analyse this.

page load time if 200 response on previous stage - load data...

resources (css, js, img ...) load time @ stage measure not web servers performance , network latency, yours. should parse received html, find links resources, , repeat first step (open socket) or download them via httpclient or smt else...

also you should remember http/2, gzip...
