Faster file transfer speeds

Faster file transfer speeds

The default FlashFXP configuration is intended for maximum compatibility. FlashFXP supports a wide range of operating systems and network configurations out of the box. In some environments this configuration might not provide optimal file transfer speeds.

Below are some configuration tips that can be used to increase the transfer speed.

Determine your maximum connection speed

www.speedtest.net allows you to perform a speed test from many global locations, in addition to determining your connection speed this can be useful if you know the geographical location of the server and will allow you to get a better idea of what to expect when transferring to this area of the world.

Adjust the TCP/IP Send and Receive Buffer sizes in FlashFXP

In some cases changing these buffer sizes can make a difference; in particular in transfers over high loss, high speed connections where latency plays an important role. Adjusting the TCP/IP Send and Receive buffer increases the TCP Window size. (Wikipedia: TCP Window scale)

The TCP/IP buffer size can be adjusted globally or per-site (FTP, FTP+SSL or SFTP). In some situations you may find that different servers require different buffer sizes to provide optimal speeds.

We've conducted extensive tests over local area networks and over the Internet in an attempt to determine the optimal buffer sizes and our results have indicated that using a send and receive buffer of 128KB or 256KB will typically provide the best results. You may find that different values provide the best result for you.

So why don't we use 128KB as default? In a perfect world we would, previous versions of FlashFXP used 128KB as default. Based on extensive customer feedback a small percentage reported that using a 128KB buffer resulted in reduced file transfer speeds and increased connectivity issues (random disconnects to the server).

Due to changes and improvements in the Windows operating system your results may vary based on the version of Windows being used.
