By default, the FTP transfer speed between the client and the server depends on many factors: Internet Service Provider limits, FTP server or client settings, etc. When this buffer gets filled, which goes very fast for 4096 bytes, it starts delaying loading additional data. Windows Explorer has a static buffer size of 4096 bytes that can’t be changed, in comparison to that FileZilla has a buffer size of 256 KB. It’s fast, being able to handle simultaneous transmissions (multi-threaded transfers), and supports SFTP and FTPS (which stands for FTP over SSL).

For download testing they provide fixed size files, you can choose which fits best to your test. Tele2 provides, you can log in as anonymous and upload anything to test your upload speed. One kilobyte equals 8 kilobits.ĥ Answers.

Most internet connections are measured in kilobits (Kb) per second. In most FTP software programs, transfer speeds are recorded in kilobytes (KB) per second. Increase Maximum simultaneous transfers to 10.Here are the instructions to increase the number of simultaneous transfers in FileZilla for faster upload and download of files: We have one system (Windows 2008 Server), where we can do a windows copy that is 100% faster than sending the same file via FTP.

Concurrent downloads increase FTP speed by allowing many concurrent connections to the server.Īll internal systems. To optimize FTP speed on the client-side, increase the parallel (concurrent downloads) or adjust the “maximum simultaneous transfers.” This feature will bypass some limitations defined by the server. Also, there are other factors which may affect the speed: The number of clients that currently are using the FTP service. This may be affected by multiple network factors such as hop count and local connectivity. FTP upload and download speed depend mainly on the client’s connection to the server.
