I have a bad download rate after using Speed optimizer can anyone help with tweaking?

Is your ISP StarHub?
Try the following custom settings 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 - 513920
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 - 96
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect
After reboot, test your speed at this link using the S'pore test server:

Your tracert does not show a router in your connection line. What Brand and model is your router and modem?
Make sure your modem is placed a few feet away from any other electrical device, including the router.

Re-install your router and make sure it does not use bridge mode. If router is functioning, all 3 ping times at hop 1 would be <1ms.

all pings at hop 1 is <1ms
i realised my torrenting download speed is very bad... upload speed is alot better now.. lol

In order to download, the comp must be able to upload. Why?
During downloading, the comp must send out timely acknowledgements to the other side that data packets have been received. If upload bandwidth is saturated and such acknowledgement cannot be sent, the other side will just resend the same data packets.
So the question for torrents is, did you limit your torrent program to only use half of your ISP give upload speed? If not, then upload bandwidth will be saturated by uploading torrents and receipt acknowledgements cannot be sent out. Thus, you will be receiving the same data packets again and again.

i see... i dont know about the upload speed but is there a way to check it?

See this link:
http://www.starhub.com/portal/site/Onli ... 4114acRCRD
You have the Premium plan - 12000/384 kbps
So you need to limit your torrent program to a global upload speed of 192 kbps or 24 KB/s.

itwont let me get to 24kbps... much less 10.. hmm...

Since you have turned your router on, you need to port forward your router.
First, you have to set your computer with a static LAN IP address. Follow the instruction of this link:
http://www.portforward.com/networking/static-xp.htm
Then go to this link and click the name of your torrent client (eg. BitComet) and follow its instructions on port forwarding:

aye its much better now... my torrents are downloading much faster now ... 24 upload and download rate of 50 is there any way to make it faster?

You can try this patch and increase your half-opened TCP Connections from 10 to 50 or 64:

What torrent client are you using? Limit your default max. connections for one task to 10 and max. connections for one task to 20. If they have been set any higher, your router will be overwhelmed by too many simultaneous connections.

im using bitlord, i am only torrenting one torrent i heard that torrenting many torrents would further increase the download speed... is that true?

The speed of each torrent depends on the speed the others are sending to you. Most of us have relatively low upload speed compared with download. Thus, we can only send out torrents at small speed.
Thus, you need to be running more torrent tasks to get a higher accumulated download speed, usually 5-12 depending on your download speed and type of router.

low upload speed then compared to download... mines the opposite... lol it was good yesterday afternoon... it can reach to about 60kb/s now is like 12 kb/s

I am now running 5 tasks. Speed for each task varies from 2-35 KB/s, with total speed at 65 KB/s.

argh even if i download like 4 tasks the maximum dl rate i can go is 12kb/s

That will depend on the no. of seeders and leechers of each task.
Try increasing no. of tasks, but make sure each have a few seeders and 8 or more leechers.

I am using BitComet.
In your BitLord, you need to change the following after applying the patch to increase no. of half-opened connections:
Option->Preferences->Connections
Max. half-opened Tcp connections: default is 10. Change this to follow the patch.

Check also if your firewall software is blocking torrents by running torrents without it.

Yup. My BitComet was also in the allowed list of my Comodo firewall and speed was at 30+ KB/s. When I turned off Comodo firewall, speed went up above 100 KB/s.
Now I do not use any software firewall, just NOD antivirus.
