not getting 3mb spped
« on: June 29, 2004, 01:24:28 pm »
I am not getting anywhere near 3mb can you give me some tweaks that will speed it up. thnx




TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
 
Default Receive Window (RWIN) = 49640
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 49640

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
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 RcvWindow limits you to: 1985.6 kbps (248.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 794.24 kbps (99.28 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 39 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.



2. Open IE and select tools - internet options - connections -

LAN settings, make sure NOTHING there is checked.



3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.



4. Clear your temporary internet files.



5. Power cycle your modem, unplug it for atleast 15 seconds.



6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.



7. Make sure you do the faster web page tweak in Read1st link.



8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.



9. Install Outpost Firewall http://www.agnitum.com\ or Sygate Firewall http://www.sygate.com/ , both have FREE and Pro versions and are heads above ZA.



10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 http://www.grisoft.com/us/us_dwnl_free.php is an excellent FREE AV app.



11. Make sure you have ALL of the latest Windows Updates

bw = 1.36 based on packet size = 10Kbits, RTT = 176.11msec, and loss = 0.0019193857442587614
The theoretical network limit is 1.36 Mbps
The transmit buffer (63.0 KByte) limits the application to 2.83 Mbps
Your receive buffer (16.0 KByte) limits the application to 0.71 Mbps
The network based flow control limits the application to 0.71 Mbps
