libvma is a LD_PRELOAD-able library that boosts performance of TCP and UDP traffic. It allows application written over standard socket API to handle fast path data traffic from user space over Ethernet and/or Infiniband with full network stack bypass and get better throughput, latency and packets/sec rate.
