File Transfer Time Calculator

Calculating File & Data Transfer Times

When calculating file transfer speeds, it's important to take into account multiple factors. The data transfer time calculator below factors in network bandwidth, file size, number of endpoints, latency and packet loss, when determining file transfer rates. While there are many technologies that can be used for file transfers, this transfer speed calculator shows how a combination of technologies can drive higher file transfer times. Try our transfer speed calculator to see how much time we can save in your environment.

Resilio Connect's data transfer protocol is optimized to overcome latency, loss, and dropped connections. The file transfer time calculator outputs above take these efficiencies into account.

When calculating data transfer rates, it’s important to understand that long distance connections bring high latency and some loss. Similar behavior happens to network transfer times when connecting over Satellite or 4G/LTE. Resilio Connect utilizes 100% of the available bandwidth in your network independent of distance, latency, or loss. Legacy transfer protocols degrade by 50-90% over lossy or latent networks.

Resilio Connect uses a combination of technologies to optimize the file transfer rate times. It combines the following technologies into a single solution:

  • Peer to peer networking,
  • Rsync-like delta encoding,
  • Data compression, and
  • WAN Optimization.

This way we can transfer large amount of data and large files over any internet connection at the optimal data transfer rates you see calculated above.

The solution also works where latency and loss are not an issue. The p2p architecture greatly improves file transfer times. By better utilizing idle network connections effective bit rate is improved. By spreading CPU and disk IO activity over multiple endpoints, we prevent data transfer bottlenecks. In a typical deployment we reduce the overall file transfer speed by a factor of 2-10x.
