Using port 81 for your ftp is fast because the port 80 (which is then used for file transfers)is prioritized by your ISP.

You can't have two services using the same incoming port and expect all to work. You either change your webserver port, or you change your ftp port.

As suggested above, using 444 should work, since your data transfers would then use port 443, which is the https port, and is often prioritized as 80 is.

So just change 81 for 444 and see what speed u get.
You won't be able to host https webpages then, but eh, not many use that.

By the way, PASV is not related to your server network configuration, but to the client network configuration.
It's needed if the client uses a gateway/router, since no server-to-client connection can be established.
The client has to use PASV, which allows it to initiate all connections itself, while the server only wait for connections and instructions to send data.
