In this case, no. At any rate, I'd never actually use the fail-over
interface for data transfer, unless the primary had died.
Another thing you can try (but it's a long shot) is to disable
TCP_NODELAY on the socket.
In OpenSSH, edit misc.c: and and put a line with just "return;" into
set_nodelay() immediately after the "socklen_t optlen;" declaration line
so it looks like this:
void
set_nodelay(int fd)
{
int opt;
socklen_t optlen;
return; /* added here */
optlen = sizeof opt;
Note that in order to test this fully you must change both server and
client.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
