I've tried many hosting providers looking the best performance and the best price without sacrificing reliability, stability. I've moved sites from exabytes.com
, then tried discountasp.net
. I moved from them due to slow performance since my clients are located in Greece. I moved to reliablesite.net
where performance was good, features very good and reasonable price. But support was not so good.
Finally I've moved to www.softsyshosting.com
where I found both performance and support to be excellent. Sites are loading very fast and full trust is there so all features of sitefinity are available. If you need help their support replies to less than 15 minutes, sometimes faster. They are there really 24x7 since I've tested them late night hours, weekends etc.
So have a look at their site www.softsyshosting
I hope the above will help many people to do not do such a large test on various providers to find a stable environment. This test period took me almost 2 years since the process of moving sites from one hosting provider to another is not so easy and takes time.
