How does this look?

TCP properties for IP = 68.x.xx.xxx ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

On a Motorola Surfboard Modem , soon to be hooked up to a Linksys BEFSR41 Router. My ISP Is Cox. I moved and i was wondering if it got any better...Its pretty fast but i wish i could just push it a little more. Im running Windows XP Pro. My Average download on ftp://ftp1.optonline.net/pub/test64 was 344

SPEED!!

Good one Gibbs. Looks fake (someone's got a wonderful cache) besides such speeds are rarely needed given today's standards and what people do on the net (sure downloading ISO images, DivX/Xvid/vob movies, etc. would be easier if the given end server actually provided such bandwidth).

My point exactly - nevertheless with 4.417 Mbps you can't complain. Anything over 1-2 Mbps is great, anything above 3-4Mbps is wonderful and 5-10Mbps is simply awesome (especially if the upload figures are up to par - say at least: 512-1024Kbps). Good luck and enjoy your speeds.

A VERY innaccurate test, your caps are 3000. Just use the FTP tests.
