Reduce server response time
In our test, your server responded in 0.69 seconds. There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.
I can only suggest the basics which is to test your server if there is an issue using some tools like Google PageSpeed Insights; this can help you to see if your server is include on an issue. Next is to remove all the plug-ins that you don't need, it can cause some sort of thing that may slow your server. Added to it, the site size varies also; the site size is somehow connected on the response time of your server. Cheers!
