Hi everyone, today I notice that my website was too slow for no reason apparently.
I did a quick debug and I "found" the first problem.
Every time I include wp-blog-header.php it taked ~ 15s
$time1 = time();
$time2 = time();
$total = $time2 - $time1;
error_log("time:$total"); //outputs "time:15"
What could be wrong? how can i debug this problem?
