The image underscores the role of Just-In-Time (JIT) compilation in the execution process of eBPF (extended Berkeley Packet Filter) code within Linux Kernel 6. Text code is transformed into binary code via a compiler, followed by verification for security and stability. Once verified, the code is loaded into memory for execution. JIT compilation plays a crucial part in this process by optimizing the code in real-time for enhanced performance. eBPF and JIT compilation have been integrated into Linux Kernel 6, serving as fundamental features that bolster performance, security, flexibility,

The diagram depicts the direct connection between CPUs and high-performance NVMe SSDs via PCIe and explains how the NVMe over Fabrics (NVMe-oF) technology extends this over a network. NVMe-oF utilizes the TCP/IP protocol to remotely transmit NVMe commands, and NVMe-oF TCP enables stable data transfers over this protocol, meeting the demands for handling large volumes of data in environments like data centers.
