| |
Hello,
On different conferences I see that people are trying to accelerate network with putting packet processing with protocol level completely to user space. It might be DPDK, ODP or AF_XDP plus some network stack on top of it. Then people are trying to test this solution with some existence applications. And in better way do not modify application binaries and just LD_PRELOAD sockets syscalls (recv(), sendto() and etc). Current recv() expects that application allocates memory and call will "copy" packet to that memory. Copy per packet is slow. Can we consider about implementing zero copy API calls friendly? Can this change be accepted to kernel?
What are your thoughts?
Thank you, Maxim.
