![]() In particular, data copy from socket buffer to persistent memory comes at significant cost. Persistent memory eliminates a bottleneck of disks/SSDs because of 2-3 orders of magnitude lower access latency, which makes the network stack be a bottleneck even when the application persists receiving data. Arriving messages create a long queue of ready sockets where each must be processed by a pair of read/write system calls If the application is notified of 100 messages on parallel TCP connections, it requires 200 system calls to process this single event, significantly reducing throughput and increasing end-to-end latency. Suppose a server that runs a poll/kqueue event loop to handle concurrent TCP connections. Today’s socket APIs are already unable to serve on 10 Gbps under message-oriented workloads. New hardware, such as high-speed NICs and persistent memory introduces significant challenges in system software design and implementation. We describe design and implementation of PASTE, as well as how to write applications on top of it. We introduce PASTE, an extension to the netmap framework for end systems to exploit high speed NICs, kernel TCP/IP stack and emerging persistent memory.
