Hi,

Working with slapd under heavy load it could be interesting to have TCP buffers
size configurable at slapd application level instead of getting default OS
values.

Some fast modifications in daemon.c file to achieve a hardcoded value for the
sender buffer are:

		int buf_size = 1572864; /* 1.5 Mb */
		rc =setsockopt ( s, SOL_SOCKET, SO_SNDBUF, (int*)&buf_size,
sizeof(buf_size));
		if(rc==-1) {
			Debug( LDAP_DEBUG_ANY, "slapd(%ld): "
				"setsockopt(SO_SNDBUF) failed errno=%d (%s)\n",
				(long) l.sl_sd, err, sock_errstr(err) );
		} else {
			Debug( LDAP_DEBUG_ANY, "slapd(%ld): setsockopt(SO_SNDBUF) to %d\n",
				(long) l.sl_sd, buf_size, 0);
		}

Regards,

Evaristo
