After doing a test on DSLReports.com

Your Tweakable Settings:

Receive Window (RWIN): 256960
Window Scaling: 2
Path MTU Discovery: ON
RFC1323 Window Scaling: ON
RFC1323 Time Stamping: OFF
Selective Acks: ON
MSS requested: 1460
TTL: 65
(less any hops behind firewall)
TTL remaining: 51

This is what it told me,
(Problem)Choose RWIN between 5840 and 13140

Example 146000 byte download

Actual data bytes sent: 176660
Actual data packets: 121
Max size packet sent: 1500
Max size packet recd: 1500
Retransmitted data packets: 21
sacks you sent: 11
pushed data pkts: 4
data transmit time: 1.743 secs
our max idletime: 358.9 ms
transfer rate: 68107 bytes/sec
transfer rate: 544 kbits/sec
This is not a speed test!
transfer efficiency: 82%

This is what it told me,
(Problem)Some re-transmissions seen

ICMP (ping) check

Minimum ping: 90 ms
Maximum ping: 110 ms
Ping stability:
100 91 91 110 91 90 91 100 90 92

This is what it told me,
(Something Good)Looking good

Can someone tell me what they think?
I have win2k ntlworld with patches installed from Speedguide :confused:

(#705) The tweak tester reports retransmissions (back)
The purpose of TCP is to cope with links that may exhibit packet loss, or may even allow packets to arrive out of order, or in duplicate.
The tweak tester can notice packet retransmissions during the test file transfer. this is not a disaster.
The internet has weather, and the weather is not always sunny.. when there are storms, (congestion or other problems en-route), packets can get dropped and must be sent again.
Persistent, and high number of retransmissions may also be due to a high RWIN (receive window) on your end, which is why they are reported.
Retransmissions of data reduce throughput, reducing the speed at which you receive data. Particularly lossy links (perhaps representing ISP congestion, or even problems on your own line), play havoc with download speeds even reducing them to a crawl.
A line quality test may reveal more about the source of your packet loss problems.
