What ever happened with this? "eXperimental

First off, thank you everyone who has helped me with this.
After the reading that I have been through this is basically what I've come
throughput = window size / RTT
Which means that if I want a 5Mbit/s throughput and my RTT is 220ms then I
want a window size of 137,500 bytes. Is this inaccurate???
Besides these two sysctls are there any other changes that I should make to
Namely should I tweak/enable these sysctls?
net.inet.tcp.msl (The Maximum Segment Lifetime for a packet.)
net.inet.tcp.slowstart_flightsize (The number of packets allowed to be
in-flight during the TCP slow-start phase on a non-local network.)
net.inet.tcp.newreno (Enable TCP NewReno Fast Recovery algorithm, as
described in RFC 2582)
I started this thread with a discussion of these features, I am now under
the impression that I do not want to enable/use these sysctls.
Thanks again everyone for their help!

For that just follow:
And make sure you have met your requirements between A & B. Once that is
done and confirmed working you can start thinking how to do the proxy
things. There are quite a few ways to do it depening on what sort of use,
user population, number of ftp sites behind the proxy, internet or not,etc.
