SUMMARY

FTP uploads using Windows Explorer and Internet Explorer are slower than FTP uploads with the command prompt. This is because Windows Explorer and Internet Explorer have a default send buffer size of 4096 bytes. Due to this default size, FTP uploads initiated from Windows Explorer and Internet Explorer will be slower when compared with command prompt.

Note: This buffer size is not configurable in current versions of Windows.

MORE INFORMATION

ftp.exe with command prompt does have a configurable send buffer size. To specify a custom buffer size in the command prompt, type in:

ftp.exe -x: buffersize in bytes (for example: 8192)

You will then see the following message:

SendSocketBuffer: 8192 Bytes

The send buffer size is now set for this session and you can then proceed with the FTP connection.
