I've had to do this all again after a hard drive failure.
Done the speed tests, ran cablenut, tcp optimizer results below.
But in cablenut, my RWIN already IS 64240
connection still slow, whats going on?

SpeedGuide.net TCP/IP Analyzer


TCP properties for IP = ........................ ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 020405b401010402
 
MTU = 1500
MTU is fully optimized for broadband.
 
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
 
Default TCP Receive Window (RWIN) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 17520

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
 64240 (MSS x 44)
 
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 700.8 Kbps (87.6 KBytes/s) @ 200ms
Your TCP Window limits you to: 280.32 Kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
 
MTU Discovery (RFC1191) = ON
 
Time to live left = 118 hops
TTL value is ok.
 
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
 

I know, its weird, even when i clear the boxes and select "retrieve registry values" it still says 64240

Tiscali 1mb

Ok, that worked, although i had tried it earlier.
speed tests still poor tho

Hi wrc,

I forgot what your advertised speed is. Please do a speedtest and post.

Also check to ensure your signal cables and devices are plugged firmly and not placed near to other electrical devices - keep modem and router a few feet apart.

what speed do you get here?

This is true for anyone.  P2P file sharing depends on a zillion factors.  I have rarely noticed download speeds anywhere near my cap with torrents, etc. even when there are a lot of seeds.  Usually it sits at about 5% of my cap, on average.  Just because you don't see maximum speed in downloads of this nature, doesn't mean that there is anything wrong on your end.  P2P networking is unreliable and always will be.
