Can someone help me with my setup? These are the results with the programs you recommended.
TCP properties for IP = xxxxxxxxxxx (pool-141-152-168-193.norf.east.verizon.net)
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
 
TCP options string = 0204055001010402
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1360
Maximum useful data in each packet = 1360, which equals MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 65280
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65280
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
bandwidth * delay product:
Your RcvWindow limits you to: 2611.2 kbps (326.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1044.48 kbps (130.56 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON

Time to live left = 116 hops
TTL value is ok.

I ran speedtest and this was the result every time. I emptied the cache each time too!

PPPOE

Thanks much!
OS is win xp

Welcome to the Forums chrisw , are you using AOHELL? Your MTU is 1400 and AOHELL is the only ISP I know of that limits it to this. I believe Verizon is PPPoE, if so your MTU should be 1480. We need to set your MTU properly before we can optimize anything else. If AOHELL is installed I highly suggest uninstalling it then repost another TCP/IP Analyzer test, if you are not using AOHELL click the link to the left "DSL PPPoE Help" and follow the directions for setting your MTU properly.

AOHELL    AOHELL   i got mail yeah yeah i got mail  

[chrisw]

I had aolhell installed on the computer. It came with it and I never used it. I hated it too much too use it.

OK uninstall AOHELL then reboot and try another TCP/IP Analyzer test.

OK try the following fix for your MTU:

AOL MTU Fix:*this can also needs to be changed even if AOL has been uninstalled
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

\NdisWan\Parameters\Protocols\0 - look to the right for the value named "protocol MTU" and change it to the appropriate MTU value for your connection.

You should set it to 1480, set it and reboot and run another Analyzer test and see what your MTU is.
