Yes, the sliding window property of TCP/IP is adjusted. Please have a look at my initial posting and you'll find out that I compared the throughput of ICS FTP demo server to that of the Indy10 FTP demo server on the same computer using the same connection. Today I have found out that the problem is solved for this special case when increasing the BufSize of tWSocket to large values (around 1MB gives a throughput of ~7.7MB/s). Now my question is if it is a good idea to use such big buffers for file transfers in general. /Tobias -- NOA Audio Solutions Vertriebsges.m.b.H.
