Posted this over at www.planetamd64.com but thought I would echo it over here as it is something I want solved really, cos it is well annoying When my inbound connection is completely maxxed out, which on my 2meg line may well be between 150-250kb/sec or a 240-260kb/sec download (ie last nights vista ctp) I have various connection issues that seem to occur. I thought it may well have been Azureus hogging all these connections that I apparently increased to 600 (although I guess that makes no difference?) but as I was downloading Vista last night I noticed the same thing, the symptoms are: - General connections are slow (but thats to be epxected if you are maxing things out!) - Mail will not send in Outlook - Uploading files to FTP will get stuck at 0.0kb with FlashFXP - Submitting data in forms (usually my forum templates or news articles) will fail although the page will continue to redirect to the .php with no argument and the data won't be added (VERY frustrating) Has anyone experienced anything like this? If it helps I am using the onboard NVIDIA network connection, with the latest nforce drivers available. No firewall (well AVG but it was happening before I used that) This did not used to happen on Windows XP 32bit, and stopped happening when I moved from x64 to x86, but I have migrated back again and it has once again started happening.
