Need to measure all parameters
to understand effects of
parameters, configurations:
Windows, streams, txqueuelen,
TCP stack, MTU, NIC card
Lot of variables
Examples of 2 TCP stacks
FAST TCP no longer needs
multiple streams, this is a major
simplification (reduces #
variables to tune by 1)
Stock TCP,
1500B MTU
65ms RTT
FAST TCP,
1500B MTU
