Using remote mySQL-Database very slow

Because we have no possibility to run an AgileTrack server, we tried to use a mySQL-Database in the internet (that means not localhost, but remote access). Unfortunately this is extreeeeeemly slow (That means at least 30 seconds are needed to load an issue, sometimes the application doesn't respond anymore at all). OK, probably AgileTrack was not designed for that ;-) But other Tools (mySQL Query Tools and so on) work perfectly and even quite fast.

Have you any idea what we can do? We would really like to use AgileTrack in the future, but we need a possibility for access over the internet – without a special server, since we have nobody who can run it. Is there somebody that hosts an Agiletrack a server? Or can the data transfer between database and application be optimized?
