Newbie would like to Tweak

[03viper]

Hi All, Newbie here, know nothing about tweaking and would like to give it a try, (with your help ofcourse)
1. not sure would it be ISDN what's the difference
2.Xplornet 1.0Mbps / 256Kbps

3. Here's my log

Any help would be greatly appreciated.

Thanks

Try the following with TCP Optimizer:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64
TCP Receive Window - leave blank
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 - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

After reboot, post a new TCP Analyzer report.

estimate = 1.84 based on packet size = 11Kbits, RTT = 48.12msec, and loss = 0.015555556
The theoretical network limit is 1.84 Mbps
The NDT server has a 105.0 KByte buffer which limits the throughput to 17.04 Mbps
Your PC/Workstation has a 32.0 KByte buffer which limits the throughput to 5.19 Mbps
The network based flow control limits the throughput to 3.67 Mbps

Client Data reports link is 'T1', Client Acks report link is 'Dial-up'
Server Data reports link is '10 Gig', Server Acks report link is 'T1'

TCP Analyzer reported correctly that your TCP Window is set to 32768.

Did you install some active speed tweak software and it is still running in the background? - eg. cFoS

No, newly reformated computer, however, did have system mechanic 7 on, then deleted it.

Clean your comp and scan for issues with CCleaner. Then reboot comp and use WinSockFix again.
