splitriff Posted July 14, 2007 Report Share Posted July 14, 2007 Suddenly, about exactly after I updated to version 1.7.1 my downloads would not exceed 80 kb/s and the entire network became unbearable to surf on.I have explored the forums and searched the problems, but cannot find a solution. I have vista ultimate, 3.5gb P4 w/ 1g ram, asus mobo etc. I have my ports forwarded through the firewall and router which were working just fine until the update. I have downloaded the tcpip patch and have tried changing my max half open. I have tried limiting my max connections, limiting connections per torrent. i have tried high seeder/low leecher torrents that i have already downloaded previously at very high speeds. My isp is verizon and i can usually obtain download speeds 150kb/s+ but am very obviously capped. my upload speed is above 6 kb/s. I have also tried going back to previous versions as far back as 1.4 and have seen the exact same problem. I have changed my port to above 6000 to help interfere less with websites, but any internet surfing is just a little bit faster than dialup from any computer in the network when utorrent is running on my machine. as soon as utorrent is off, the network is running full speed again. my computer shows no memory leak or high cpu usage, although utorrent now briefly freezes before closing. I have tried adjusting settings with the cache to the hard drive with no results. there arent any other programs interfering as far as i can tell. Feel free to ask anything i have left out, and Please Help!! Link to comment Share on other sites More sharing options...
Firon Posted July 14, 2007 Report Share Posted July 14, 2007 Have you tried turning off DHT? Link to comment Share on other sites More sharing options...
Ultima Posted July 14, 2007 Report Share Posted July 14, 2007 Well, you're missing the specifics about what you limited the connection stuff to. Link to comment Share on other sites More sharing options...
splitriff Posted July 14, 2007 Author Report Share Posted July 14, 2007 I have tried limiting my max connections to 10, 20, 50, 100, 200, 250. and i have tried limiting my connections per torrent to 5, 10, 20, 25. also, i have my encryption enabled and legacy connections allowed. i cannot reach speeds above 85 kb/s and it varies somewhere between 75 and 85, but does not maintain a constant rate Link to comment Share on other sites More sharing options...
Ultima Posted July 14, 2007 Report Share Posted July 14, 2007 What have you tried lowering net.max_halfopen to? Have you tried something like 2? Link to comment Share on other sites More sharing options...
Switeck Posted July 14, 2007 Report Share Posted July 14, 2007 Did you try disabling DHT, UPnP, and Resolve IPs?Did you run Speed Guide (CTRL+G) and choose nothing higher than xx/256k...or maybe xx/384k? Link to comment Share on other sites More sharing options...
splitriff Posted July 15, 2007 Author Report Share Posted July 15, 2007 i have disabled DHT with no results, disabled upnp with no results and i am unclear on resolving IPs. i set my ip address in the blank selection in the advanced options which i believe is resolving my IPs. all these have had no change on or off. I will try lowering my net max half open to 2 but have had no luck setting it at any number Link to comment Share on other sites More sharing options...
5618 Posted July 15, 2007 Report Share Posted July 15, 2007 Go to the Peers window and if you see peers in there, right-click in the tab and disable host resolving. That's how it's done. Link to comment Share on other sites More sharing options...
splitriff Posted July 15, 2007 Author Report Share Posted July 15, 2007 disabling host resolving has gotten my browsing speed back up and now i have speeds well over 100 kb/s! thanks so much. one last request, could you explain host resolving briefly so i can better understand what happened and why its fixed?

5618 Posted July 15, 2007 Report Share Posted July 15, 2007 Having it enabled does a reverse DNS lookup for the IP to try and find a hostname entry. Some setups or hardware (routers) can crap out when too many of these requests get sent out. Link to comment Share on other sites More sharing options...
