Mark Russinovich On Vista Network Slowdown
koro666 writes "In his latest blog post, Mark Russinovich analyzes the network slowdown experienced by some users when playing multimedia content. 'Tests of MMCSS during Vista development showed that... heavy network traffic can cause enough long-running DPCs to prevent playback threads from keeping up with their media streaming requirements, resulting in glitching. MMCSS' glitch-resistant mechanisms were therefore extended to include throttling of network activity. It does so by issuing a command to the NDIS device driver... [to] pass along, at most 10 packets per millisecond (10,000 packets per second)... [T]he networking team is actively working with the MMCSS team on a fix that allows for not so dramatically penalizing network traffic, while still delivering a glitch-resistant experience.'"
Soviet Russinovich analyzes You.
I've been using Vista for 6 months now. I upgraded my XP Media Center edition. Upgrade took a long time, but everything works. No crashes. It is plenty stable and fast. I like the UI and especially the multimedia tools for photo and video. The only annoyance I've noticed is that DivX software likes to trigger the "Cancel or Allow" thingy.
