However smaller buffer like 64K buffer and at higher latency delay time levels then standard 64K buffer don't be giving you much speeds because latency delay times can reduces speeds so greatly in effect. My Linux PC ---> My cable modem that's it so I can get much faster speeds without using router hardware device since Linux includes flexible iptables and ip6tables firewall functionality. Hope that helps. P.S. if 64K congestion window fills out a buffer at one ms RTT really definitely gives you up to 500 Mbits but unforateunly 64K congestion window can't stand at 100 ms delay and degrades to 5 Mbits speeds down that is explain. Unless if you start with 64M buffer at 100 ms delay that could gives you 5 Gbits speeds that is very simple ;) And smaller buffer and higher latency delay times will take longer time and higher buffer and higher latency delay times will take much less time to get there. smaller buffer at higher latency delay times really definitely extrmemly inefficient for high speed broadband WAN link.

here's my test speed of bewteen my home in Wichita, KS and test speed site in Denver, CO over 400 miles of distance in about 100 ms delay with greater congestion window side buffer that gives me greater speeds that is very simple



So I can ignore packet delay as same as packet loss since larger window buffer are much sufficient enough.

Someday I will be professional IT either software programmer when I get into university school ;)

I can access to sega.jp web site reachable in japan country really fast enough with larger window buffer.

Linux does have congestion window dynamically implantment as optional since 2.4 Linux kernel and now newer 2.6.xx Linux kernel have enabled of congestion window buffer dynamically, window scaling as automatically tune at default setting.

Larger congestion window buffer size with window scaling enabled really can help to keep congestion window from collapsing of data stream of broadband or dedicated high speed bandwidth in the packet delay times and the high latency of environmental.
