Hi Shashank,

To optimize Vuze download speed, you can try the steps below...

STEP 1. Open Vuze and select a suitable network port. To do this, go to Tools in the Vuze interface. Then, click Options. Click Connections and select advanced for skill level. Then, TCP/UDP listen ports should be set to 65534 -- Go to http://www.canyouseeme.org/ to check if your port has been properly configured...

STEP 2. Forward your newly configured port through your network\'s firewall and router. You can do this by going to Tools in the Vuze interface. Select Options. Next, click Plugins and select UpnP. At this point, check both the “Enable Upnp” and “Automatically refresh mapping when NAT status is firewalled” checkboxes. Next, click Tools in the Vuze interface. Click Options and select Plugins. At this point, click Upnp and select NAT-PMP. Check the “Enable” checkbox.

STEP 3. Configure download and upload settings of Vuze to match both your computer and your network\'s upload and download speed. You can do this by knowing your upload speed. Install Flash and enable JavaScript in your browser before going to http://www.speedtest.net/ so as to check your upload capacity in KB. Then, take note of your upload speed capacity in KB and enter it in http://infinite-source.de/az/az-calc.html so as to get recommended settings. Next, go to Tools in the Vuze interface and select Options. Then, click Transfer and input your recommended settings...

STEP 4. Configure peer sources and encryption settings in Vuze. You can do this by going to Tools in the Vuze interface. Then, select Options. Click Connections and check all provided checkbox options. Keep in mind to place a check beside the DHT (Distributed Hash Table) and PEX (Peer Exchange) checkboxes. Then, go back to Tools and select Options. Click Connections and select Transfer encryption. At this point, check all provided options...

That\'s it. Also keep in mind that LAN or WAN and Internet connection lags may also be caused by some errors in your PC, improperly configured system settings and mismanaged OS functions.
