Filemail has servers in Central Europe, Scandinavia, Australia and across the USA. Datacenters have core networking supplied by Level3 (2x10 GBit), Deutsche Telecom (2x10 GBit), and Global Crossings (2x10 GBit).

The up-and-download speed depends on your internet service as well - you can check your speed on sites like: http://www.speedtest.net to compare the speed you are getting with Filemail with the one you should get.

What needs to be taken into account with the above Speedtest is that generally, they use a receiving server very near to your location, thus not taking into account internet traffic at various locations.
