In eMule MorphXT the developers tried to improve all the default configurations, because eMule required a large amount of configuration modifications to be able to reach an optimum point in what regards to downloads and transfers. That is why this mod was launched totally configured to be able to offer the best performance.
Likewise, eMule MorphXT includes a backup system the intention of which is that you never lose the downloaded files and specially those that have still not finished downloading. Furthermore, it also includes a powerful anti-leecher that manages to make sure that those users that share less aren't well received.
In what regards to the connections, the truth is that eMule MorphXT is very quick when it comes to connecting to any server and in the searches it finds a vast amount of files with many sources, which makes it easier for them to be downloaded.
Is it better than the original eMule? Only you will be able to find out.
