Here is my system and info I get from TCP/IP Analyser.

AMD 1.333 Tbird (266FSB)
512 Meg Crucial CAs 2 Mem
Leadtek Gforce 2 Pro 64 Meg DDR
75 Gig IBM ATA 100
A-open K73 Pro-A MB
Sound Blaster Platinum 5.1
Yamaha 16 X CD/R/W

I am using the Linksys Single Port Router on my @home network.

------------------------------------------------------------------------------------
TCP options string = 0204059c010303030101080a000000000000000001010402

MTU = 1476
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 = 1436
Maximum useful data in each packet = 1424, which is less than MSS because of Timestamps, or other TCP/IP options used.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 524176
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 65522
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
505472 (MSS x 44 * scale factor of 8)
252736 (MSS x 44 * scale factor of 4)
126368 (MSS x 44 * scale factor of 2)
63184 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 20967.04 kbps (2620.88 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8386.816 kbps (1048.352 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 19 hops
TTL value is ok.

Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000




565280 connections tested since 03.10.2001.
Analyzer version: Beta 0.99

I beleive your MTU should be higher, you may need lastest Linksys Firmware here (http://www.practicallynetworked.com/support/linksys_router_help_pg2.htm) :) :) :)
