hi,
im running some experiments, and it seems to me that
setting net.inet.tcp.rfc1644 has the reverse effect.
with sysctl net.inet.tcp.rfc1644 = 0, the transaction uses only 6 packets
and it's less than 1 sec, setting net.inet.tcp.rfc1644 to 1 uses
8 packets and takes more than 1 sec.
with net.inet.tcp.rfc1644 = 0:
