Can someone help me with my setup? These are the results with the programs you recommended.
TCP properties for IP = xxxxxxxxxxx (pool-141-152-168-193.norf.east.verizon.net)
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
TCP options string = 0204055001010402
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1360
Maximum useful data in each packet = 1360, which equals MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 65280
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65280
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of

261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
bandwidth * delay product:
Your RcvWindow limits you to: 2611.2 kbps (326.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1044.48 kbps (130.56 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 116 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000

I ran speedtest and this was the result every time. I emptied the cache each time too!

Thanks much!
