eMule is a filesharing client based on the eDonkey2000 protocol. Which means you are able to connect to official eDoneky2000 clients and visa-versa usign eMule.

Some factors that influence the download speed:
· eMules settings
· High ID (Firewall and router settings)
· Duration of the eMule session
· Number of sources for a download
· Availability of single parts
· Popularity of the download

Wrong settings in eMule (wrong limits, too many connections), a low ID and a short sessions durations have a bad impact on download speed. Very popular files (new releases) and generally files with a low number of sources or bad part spreading also cause low download rates.
