First of all, thanks in advance to any of you that can help me. I really appreciate whatever help I can get.
Below is my current information.
1. Operating System
Windows XP Professional with SP2
2. Internet Service Provider
Comcast - 6000 / 786
3. Tweak Programs
I've installed CableNut and TCPOptimizer
SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = XX.XXX.XXX.XX ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727)
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b40103030401010402
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) = 749568
RWIN Scaling (RFC1323) = 4 bits (scale factor of
Unscaled TCP Receive Window = 46848
For optimum performance, consider changing RWIN to 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: 29982.72 kbps (3747.84 KBytes/s) @ 200ms
Your TCP Window limits you to: 11993.088 kbps (1499.136 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 49 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00100000 (32)
Precedence (priority) = 001 (priority)
Delay = 0 (normal delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 0 (normal cost)
Check bit = 0 (correct, 8th checking bit must be zero)
DiffServ (RFC 2474) = CS1 001000 ( - class 1 (RFC 2474). Similar forwarding behavior to the ToS Precedence field.

estimate = 4.49 based on packet size = 11Kbits, RTT = 54.16msec, and loss = 0.002100105
The theoretical network limit is 4.49 Mbps
The NDT server has a 8192.0 KByte buffer which limits the throughput to 1181.77 Mbps
Your PC/Workstation has a 732.0 KByte buffer which limits the throughput to 105.59 Mbps
The network based flow control limits the throughput to 6.37 Mbps
Client Data reports link is 'T1', Client Acks report link is 'T1'
Server Data reports link is '10 Gig', Server Acks report link is 'Ethernet'
