Speed Up WordPress: Performance & Security
Are you testing your WordPress site speed from Pingdom, Gtmetrix, pagespeed insights?
Just STOP NOW using those tools. Get accurate pagespeed metrics from webpagetest.org.
Don’t judge your site load time by testing only one page (many check homepage). In my case, i’ve 100 posts and 3 pages including home page. I optimized my site in a such way that any post will load under 1 sec. Try to get the best pagespeed score or load time for 100 posts instead of only homepage or category pages, etc.
