Lyor Goldstein commented on SSHD-1075:
--------------------------------------
Note that increasing buffer size does not necessarily increase throughput -
1st, SSH defines a max. packet size of ~32K, and 2nd, the TCP itself cannot
send more than ~1400 bytes per packet... In other words, you might decide to
use a 1MB buffer, but it will be broken down to smaller and smaller packets
anyway. Each packet has a (more or less) fixed processing and delivery overhead
so increasing buffer size does not necessarily increase throughput.
> how to configure TCP receive buffer, SSH receive buffer, and SFTP receive
> buffer ?

> For TCP Receive Buffer i can map it to FactoryManager.
