sessionWindowSize

Receive window, in bytes, for shells, commands and manually opened subsystems. SFTP channels opened by SshClient.openSftp use sftpWindowSize. A channel moves at most one window of data per network round trip, so a larger window speeds up bulk transfers on slower links. Each channel may buffer up to this much unread data. Default: 2 MiB. Reduce this for sessions with tighter memory limits.
