I've been experiencing a significant slow down of my home internet connection. ISP sent over some engineers and they didn't think there was an issue with the setup or the connection. All they did was a ping google.com -t test and the ping ran without any timeouts.
Since my pages keep timing out, I ran the NDT test from http://www.measurementlab.net/run-ndt. Here's what I got:
Your system: Windows 7 version 6.1 Java version: 1.6.0_27 (x86)
TCP receive window: 114176 current, 135936 maximum 0.001331558 packets lost during test Round trip time: 285 msec (minimum), 1193 msec (maximum), 712.7 msec (average) Jitter: 908 msec 0 seconds spend waiting following a timeout TCP time-out counter: 816 140 selective acknowledgement packets received
No duplex mismatch condition was detected. The test did not detect a cable fault. No network congestion was detected. No network addess translation appliance was detected.
0.5014% of the time was not spent in a receiver limited or sender limited state. 45.839999999999996% of the time the connection is limited by the client machine's receive buffer. Optimal receive buffer: 139198464 bytes Bottleneck link: Cable/DSL modem 0 duplicate ACKs set
So, is there an issue with my machine's/router's "receive buffer"? (WTH is a that anyway?) :) Anything I can do to fix this?
