Eerst denk je .....simpele output:

TCP/Web100 Network Diagnostic Tool v5.3.3a

Your PC is connected to a Cable/DSL modem
Information: Other network traffic is congesting the link

The NDT server has a 8192.0 KByte buffer which limits the throughput to 454.31 Mbps
Your PC/Workstation has a 250.0 KByte buffer which limits the throughput to 13.91 Mbps
The network based flow control limits the throughput to 0.31 Mbps

Web100 reports the Round trip time = 148.79 msec; the Packet size = 1452 Bytes; and
There were 21 packets retransmitted, 34 duplicate acks received, and 42 SACK blocks received
The connection stalled 5 times due to packet loss
The connection was idle 1.8 seconds (18.0%) of the time
This connection is network limited 99.89% of the time.
Contact your local network administrator to report a network problem
Contact your local network admin and report excessive packet reordering
Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch

Dit zie ik

Probeer deze eerst is... https://www.speedguide.net/files/TCPOptimizer.exe .... want deze staan nog allemaal disabled :

RFC 3168 Explicit Congestion Notification: OFF
RFC 1323 Time Stamping: OFF
RFC 1323 Window Scaling: OFF

Ik heb geen idee hoe ik
RFC 3168 Explicit Congestion Notification: OFF
RFC 1323 Time Stamping: OFF

op On kan krijgen

RFC 1323 Time Stamping: OFF    -->
SG TCP proggie starten, custom settings, TimeStamp en blackhole detect aanzetten en applyen


Die andere zoek ik ff uit!

Hebbie ook al die Winxp tweaks geprobeerd van speedguide?

Het programma geeft aan wat de beste instellingen zijn.
Dus timestamping moet moet niet aan, maar uit staan

Owkee.... zet ik die ook weer uit! Thanks.

Kan nog niks vinden over die congestion.... die blijf ik ook maar houden.
