Since the first question is answered above, i will give my answer for the second.

How to increase the speed of the loading page?

The best is to make sure both your website and your website's host / server is optimize. As for the server side. Make sure that your server has fast network (100mbps / 1gbs port), it's good if you can host your website in the cloud.

The other one is website optimization (I prefer that you do this first before you go with upgrading your server). Try to optimize your site as much as possible. I'll list what you can do.
- Use sprites for your images, optimize your images for the web. If you do it by css then do it.
- Remove as much as image as possible.
- Try to minimize your css and js files as much as possible. There are online tools that can do this.
- Compress your css files and js files into a single file if possible to minimize http requests.
- Use CDN on your video and image contents.
- If your using server side languages (PHP), make sure that it's optimize, efficient and would run as fast as it can.
- Use caching methods.

There are still some ways to make sure your website load as fast as possible but following what I mentioned above will really cut down your loading time.
