Hi all again,

I've been playing with SO_RCVBUF to limit the download and it works. The way I've achieved is really the worst - set SO_RCVBUF to some value(e.g., 1024*15) and sleep(1) so it transfers at 15 KiB/s. The bad thing about this approach is that the sleep call blocks the main loop and pretty much everything else. If I put every socket on a separate thread it would actually kill the performance of the application when I have more than 30-40 connections. So I've read about the TCP window and I *think* what I need to do is control the acknowledgment of the received data i.e., acknowledge as much as I want to limit the download speed. So my question is which function is actually sending the transfer ACK? As Scott Ribe previously stated that calling read() every now and then has no effect I presume it's not read() which ACKs the transfer.

Regards
