Re: Hawaiian Telcom DSL
It seems like all the slow downs were caused by Hawaiian Telcom. I did not change any settings and I'm still using my 50ft phone cord for the connection that "supposedly" picked up a lot of noise and reduced my speed below 1 Mbps. Recently this week I noticed that I was connected at maximum speed consistently.
WEB100 Enabled Statistics:
Checking for Middleboxes . . . . . . . . . . . . . . . . . . Done

------ Client System Details ------
OS data: Name = Windows XP, Architecture = x86, Version = 5.1
Java data: Vendor = Sun Microsystems Inc., Version = 1.5.0_08
------ Web100 Detailed Analysis ------
Cable modem/DSL/T1 link found.
Link set to Full Duplex mode
No network congestion discovered.
Good network cable(s) found
Normal duplex operation found.
Web100 reports the Round trip time = 241.02 msec; the Packet size = 1460 Bytes; and
No packet loss was observed.
This connection is receiver limited 95.36% of the time.
Increasing the current receive buffer (38.0 KB) will improve performance
This connection is network limited 4.33% of the time.
Web100 reports TCP negotiated the optional Performance Settings to:
RFC 2018 Selective Acknowledgment: ON
RFC 896 Nagle Algorithm: ON
RFC 3168 Explicit Congestion Notification: OFF
RFC 1323 Time Stamping: OFF
RFC 1323 Window Scaling: OFF
Packet size is preserved End-to-End
Server IP addresses are preserved End-to-End
estimate = 46.22 based on packet size = 11Kbits, RTT = 241.02msec, and loss = 1.0E-6
The theoretical network limit is 46.22 Mbps
The NDT server has a 1088.0 KByte buffer which limits the throughput to 35.28 Mbps
Your PC/Workstation has a 38.0 KByte buffer which limits the throughput to 1.24 Mbps
The network based flow control limits the throughput to 1.29 Mbps
Client Data reports link is 'T1', Client Acks report link is 'T1'
Server Data reports link is 'T1', Server Acks report link is 'T1'
It looks like Hawaiian Telcom added more bandwidth since the theoretical network limit was increased to over 45 Mbps. In addition, there is no network congestion nor is there any packet loss. I used to have both problems before.
I am dismayed that Hawaiian Telcom didn't tell me or any of their customers upfront that the slowdowns were caused by their end. However, I'm finally happy that I'm getting max speeds.
