Always Free slow connection?

I'm using the oracle always free to host a minecraft server, and I don't really get all the features either, just following the guide and improving where I can.

So far, the server is fine, but it seems my connection to it is rather slow. Logging in ingame takes a while, and using FTP (filezilla) to connect to it, file transfer is only like 300KB/s. Is there anything I can do to improve this?

I'm also kinda the only one with this issue on the server. My friends (from other countries) doesn't have similar issues. I assumed it's some kind of routing issues between my ISP to the oracle server.

For reference, I'm from Indonesia and the server region is singapore.
