While no hosting company is perfect, I’ve found Hostgator one of the best I’ve worked with for Linux type hosting. I host this blog (https://peterkellner.net) at Hostgator and have recently noticed the site has been kind of slow. I emailed them to ask them to look into it and the email below was there response.
As far as I’m concerned, this is way above and beyond what I should expect from a pretty low cost wordpress hoster. They could have just said it’s slow but it’s your software and you need to figure it out but they did not. Below was their response which I consider excellent!
Firstly, I'd like to apologize for the delay in our responses. Ticket queues are much longer than we'd like right now, but we still try to answer each ticket diligently. Thank you so much for your patience!
I looked into the server logs and found no evidence of a server-wide performance problem on 24 January 2014.
Then, I performed two separate tests and found that it's actually your site itself with the performance problem:
Both show that there is a significant delay between 2 and 3 seconds on <https://peterkellner.net/&ver=2.0>.
This means that your plugin WordTube is being slow on EVERY page load, regardless of caching. If you disable it, your site should should perform that much faster.
The Follow Button for Jetpack plugin is incompatible with your unusual WordPress directory structure. (You have WordPress installed in a subdirectory, `~/public_html/wp`.)
This plugin tries to fetch a file from a location it expects, but the file isn't actually there; it's in the subdirectory `wp`.
To fix the problem, you'd have to contact the developers of both plugins, as this is now a coding issue outside the scope of HostGator support.
Nevertheless, I hope this information has been helpful in pointing you to the right direction. Please don't hesitate to follow up if you have any more questions or concerns.
