I've been testing websites from web hosting companies with the help of: https://performance.sucuri.net/
I will not post any results here, but you should, just for laughing or for your own education, test the business website of your current host and that of other hosts only to see the results.
Some of the results I saw would surprise you, global page loadings with an average duration of 1.7 seconds … etc … NOT a 20X performance higher than the one announced by some, at least not in my opinion … I would NEVER accept this level of performance … anything that exceeds 0.5 seconds for charges should be a cause for concern in the current high-speed environment for SEO, customer friendliness, etc.
So, what makes these hosting company sites work so slowly? It must be a combination of poor server hardware, data centers and the software used to run the web service … or is it something else?
