can somebody take a look at my results plz?

HI Guys,

Been a while!!

Can somebody please tell me what if anything I should change here to optimise my connection? Ignore the MTU value as its the highest for PPPoA virgin. Ta!!

MTU = 1430
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1390
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 522640
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled TCP Receive Window = 65330

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
511520 (MSS x 46 * scale factor of 8)
255760 (MSS x 46 * scale factor of 4)
127880 (MSS x 46 * scale factor of 2)
63940 (MSS x 46)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 20905.6 kbps (2613.2 KBytes/s) @ 200ms
Your TCP Window limits you to: 8362.24 kbps (1045.28 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops
TTL value is ok.
Timestamps (RFC1323) = OFF Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)


Running: Windows XP Pro SP2

ISP: Virgin Net (UK) – PPPoA – up to 8MB/S

No Router – Just USB Modem direct to DSL.

63940 (MSS x 46)

TCP Window Size of 255760 may give you better speed.

Thanks man

How do i change it?

ie using DrTCPIP?

if so which window?

TTL - 64
TCP Receive Window -255760
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - checked
Timestamps - uncheck
Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 5
Host Priority - 6
DNSPriority - 7

Then select "Apply Changes" and reboot to take effect
