I upgraded to Vista Ultimate x64 last week and as you would expect from a tier
1 operating system from M$ - my reads from my trusty X6 went down from 27MB/Sec to a horrific 7MB/Sec ... oh and the old explorer hanging thing I remember well from my first Beta copy of Windows 95 was creeping back.
Long long long long long story very short - I had 2 problems
1. Machine slow and tended to hang when I was doing a lot of "netwok" tasks
2. Transfers to NAS bad (read 7MB/Sec write better at ~15MB/Sec
I tried all the things listed here, an older gigE card (RT8169) turning off services, remote compression, QoS, transport layers .... nothing. Tonight I went back to it and moved back to one of my x38's gigE ports - connected directly to the NAS box - same performance. At the same time I happened to notice my windows sidebar had thrombied so I killed it. I went to back to copy my, now very worn, 800MB test file expecting the drag and drop to show 1 minute 35 seconds and to my surprise it started at 20 seconds and ripped through it. I opened the resource monitor and copied it again 33MB/Sec OMG
Started SideBar again ....... 7MB/Sec - did this 184 times just to make sure - yup; that's what it was. Next - what in my sidebar was causing the problem - first thing killed off was the bbc live video feed - yup that's what it was. Nice feature - i'm glad I paid extra for it.
Ok so this is the first thing fixed - secondly the boggy-ness of my machine and the slow torrent downloads point at one old friend - the half open TCP connections from SP2 (I think it was 10) is still there and now it has been upped to 25. Still, a few internet gadgets, email window and a few tools that use loopback sockets and you have a TCP Q again. In the XP days there were patched versions of TCPIP.SYS files that took the limit off (search for EVID 4226 on google). This has also been done for some versions of vista, however watch the version of the TCP file. It is also more complex to install. For example, the offset patch for x64 Vista has just been released. You have to HexEdit it and re-sign it using a tool. I've just finished and the results are stunning. I remember the same when I applied this to my XP SP2 install a few years ago.

As the subject line says - if all else fails try the above - please make sure you have a bare metal recovery backup of your system though. If you are doing it in Vista x64 take extra care with the instructions, getting the signing wrong will lead to an unbootable system and you'll require to boot from CD and repair.
However - latest beta of FrontView - stunning ... bittorrent client ... very cool and handy ... performance (once I fixed Vista) ... blistering to NAS and external disks. Congratulations on your hard work.
