------  Client System Details------
OS data: Name = Linux, Architecture = armv7l, Version = 2.6.36.3-g2a65edc
Java data: Vendor = The Android Project, Version = 0

------  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 =  401.84 ms; the Packet size = 1448 Bytes; and 
4 packets retransmitted, 4 duplicate acks received, and 12 SACK blocks received
The connection was idle 0 seconds (0% of the time)
S2C throughput test: Packet queuing detected: 3.79%
This connection is receiver limited 87.86% of the time.
This connection is sender limited 1.55% of the time.
This connection is network limited 10.58% 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: ON
RFC 1323 Window Scaling: ON; Scaling Factors -  Server=1, Client=7

Server 'ndt.iupui.nuq01.measurement-lab.org' is not behind a firewall. [Connection to the ephemeral port was successful]
Client is probably behind a firewall. [Connection to the ephemeral port failed]

The theoretical network limit is 1.01 Mbps
The NDT server has a 106.0 KByte buffer which limits the throughput to 4.13 Mbps
Your PC/Workstation has a 80.0 KByte buffer which limits the throughput to 1.56 Mbps
The network based flow control limits the throughput to 1.59 Mbps

Client Data reports link is 'T1', Client Acks report link is 'T1'
Server Data reports link is 'OC-48', Server Acks report link is 'T1'
Information: Network Middlebox is modifying MSS variable
Server IP addresses are preserved End-to-End
Information: Network Address Translation (NAT) box is modifying the Client's IP address
Server says [174.253.243.130], but Client says [10.227.209.125]
