ZeroCopyÜbertragungen
ZeroCopyÜbertragungen, also known as zero-copy operations, are a technique in computer programming that aims to improve the efficiency of data transfer by minimizing or eliminating data copying between user space and kernel space. Traditionally, when data is transferred between an application and the operating system kernel, it involves multiple copies. For instance, reading a file and sending it over a network typically involves copying the data from the disk into a kernel buffer, then from the kernel buffer into a user-space buffer, and finally from the user-space buffer back into a kernel buffer for network transmission.
Zero-copy techniques circumvent these intermediate copies. Instead of moving the data, they allow the kernel to
The primary benefit of zero-copy is reduced CPU overhead and memory bandwidth usage, leading to significant
