Hello, I'm investigating my site for a while. Chrome devtools say high values for "Waiting" time for the URL. My site loads in average in 30 seconds. It's impossible to get PR this way. I don't think this would be due to programming. The site is written in php. There is no recursion or something. My browser (chrome) waits so much BEFORE it would load the page. All the requests are sent to index.php which evaluates REQUEST_URI header. The only visitor is me at this time, so I don't think it would be due to server capacity problems. Then what the hell could it be? I have another site hosted at this hosting company and it works fine. Any idea?
Found it! There was a line containing fsockopen in order to test proxy access. After removing it, it's as fast as before
