If you are on the fence as to which hosting provider is better then you need to look no further. Having hosted this site on Dreamhost for the last 3 years I decided to move my hosting to SiteGround as I was facing considerable downtimes and slow server response times with Dreamhost.
The graph below shows the moment I moved from Dreamhost to SiteGround. I have since had 100% uptime and my response times have gone from 3 seconds on average to under 1 second. I am currently in the process of moving all my sites away from Dreamhost.
