how does TransferBufferSize affect speed

Question

How does the TransferBufferSize property in FTPClient affect the overall speed of an FTP put? For example, what is the benefit of having a larger value, say 65536, versus a smaller value, say 512?

Also, how does the value of the TransferBufferSize property work on different kinds of networks - LAN vs WAN?

Any help or insight into this would help.

Thanks, Andy.

Answer 1

We're not sure it really makes any difference actually. It is a feature we might end up deprecating. We thought we'd expose the internal buffer size in case it helped in particular situations.

Answer 2

Do you have a recommended value for TransferBufferSize property based on your experience?

Also, it is important to note that the version of FTPClient.cs source I am running is Revision 1.4 2004/10/06 20:56:46. This version has hardcoded buffer size of 512.
