Noob here, a question
if i host ghost on free heroku (sleep on every 30 min)
does it affect user loading speed when user open a blog post?
You can use http://kaffeine.herokuapp.com/ to ensure that your server is pinged so it doesn’t go to sleep throughout the hours that most users access your site (note that on the free plan you have to have the server sleep 6 hours a day, which you can set to be during the hours where little users access your site).
If the server doesn’t go to sleep, loading speed should be decent (not as fast as a dedicated server though).
ic , thank for your input
