dmitryst,
Ну вы что на самом деле

Direct Cache Access (DCA) Windows 7 and 2008 Server (but not Vista) add NETDMA 2.0 (Network Direct Memory Access) Direct cache access support. Direct Cache Access (DCA) allows a capable I/O device, such as a network controller, to deliver data directly into a CPU cache. The objective of DCA is to reduce memory latency and the memory bandwidth requirement in high bandwidth (Gigabit) environments. DCA requires support from the I/O device, system chipset, and CPUs. To enable DCA: netsh int tcp set global dca=enabled Available states are: enabled, disabled. Default state: disabled Recommended: enabled (provided the CPU/MoBo/NIC support it) It is also possible to enable this setting by editing the Windows Registry instead of using netsh as follows: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters EnableDCA=1 (DWORD, entry does not exist by default. Set to 1 to enable, 0 to disable)

NetDMA это использование механизма DMA (аналогично работе винчестеров) для обмена информацией между сетевым адаптером и основной памятью вместо использования цетрального процессора и его прерываний.
