I have 5000 posts on my website, which I have uploaded from a CSV
file. This all went well and the website is fast on the back-end and frankly on any other page. There is one exception: if I click on a post, it takes 8 to 9 seconds to open a post, which is very disturbing.
I am using year/month/year/post-name as the permalink structure
and have edited the .htaccess file with the code that is outputted by Wordpress on the settings
page.
What should I do? I have used WP-Minify, but that did not have any effect at all.
FYI: it's a self hosted website, running on a fast server. The website is very fast, except at clicking on a post. Than it changes suddenly.
