I've noticed the same thing. Is this something common to the free hosting plan?
I thought initially that it could have been my connection, though a friend (on a different continent, and with a significantly better connection) informed me of the same issues.
If the lack of speed is something common to the free hosting plan (understandable, it's free after all) I'd be interested to know if the paid plans suffer the same issues before considering upgrading.
Thank you.
