Microsoft Windows 2000 TCP/IP performance has been enhanced by making the following changes to the TCP/IP stack:
 * Allowing multiple concurrent TCP segmentation offload requests to offload-capable NDIS miniports.
 * Suppressing unnecessary memory operations when hardware offloading is used.
 * Optimizing NDIS to allocate virtual memory only when requested by a network adapter driver.
