Windows A curious network performance reduction noticed by many Windows Vista users of the 2CPU forum that became the talk of Slashdot last week has been identified as having been caused not by DRM, as Slashdot users expected, but by a curious prioritization 'feature' of Vista that's intentionally biased toward Media Player at the expense of network and system resources.

It's a stupid design

The reason this happens is that an app registers with MMCSS and then the service tells NDIS to throttle the network. The network is throttled until the app deregisters or quits. It's a pretty bad, hackish design that really should go away now that everyone's running dual core machines. A better strategy would be to tell NDIS to set the TCP stack's affinity to one core and devote the other one to multimedia.
