Site running slow on new server?

I recently uploaded a website to a new 123-reg server on a single WP installation ( I had developed the site on my own hosted multisite environment (

I had a nightmare uploading the website as the standard wordpress xml export/import facility that had always worked for me kept crashing crashing. In the end I managed to get the website live using this method (

The live website is now very sluggish and nowhere near the speed it was on my test environment. I don’t know if this is down to the new server, or if something has occurred in the website move (perhaps database related) that has created the issue?

I’m not great with MySQl so don’t really have the skill to diagnose this issue (if it even is the issue) and would really appreciate some help.

And, every inexpensive host out there is slow. Check

In your head you have <link rel="stylesheet" href="css/bootstrap.css">. This is trying and failing to load bootstrap.css using a relative URL.

I would install the debug bar plugin and try to see what is going on, but if that’s not in your comfort zone, first step should be to contact your host and ask if they can help.

opening your home page is consuming around 3,5 mb bandwidth, you must reduce it.

  1. Use WP plugin for optimizing your image.
  2. Compress your .js and .css file via this site.
  3. I think you must remove css/bootstrap.css from your header file.because there is min version of this file.
  4. Use Cache plugin like w3 total cache or wp super cache.
