WebbNIC Offload: Modern NICs support offloading certain tasks from the CPU to the NIC itself, such as checksum calculation, segmentation, or even more complex operations like packet filtering. Offloading these tasks can improve performance and reduce CPU load. WebbThis recommendation stems from some buggy NIC drivers, that, when combined with TCP Offloading and multi-threaded applications can cause havoc to the NIC driver. It seems to be related to applications switching threads causing the NIC driver to switch its active TCP Offload connection in the NIC hardware and that switching process is prone to failure …
