There is an option for shared hostings that they can be moved into dedicated ip, what does it mean?
If we buy dedicated ip for our shared hosting what are the benefits could we get?
Would it be increase speed of website?
In answer to speed, only one thing can improve the speed of a Wordpress site, fewer plugins. The irrefutable fact is that the more data there is to load initially, the slower it will be.
Developer sites are the fastest normally. Far fewer lines of code for the same job, equals faster load times.
An easy proof of this is the text only web browser W3M. It is simply amazingly fast because it doesn't load any images or graphics. There is nothing faster for a web browser. When just needing info it's perfect.
