Abstract High-performance computing, just like the world at large, is continually discovering new uses for the Inter- net. Interesting applications rely on server-generated content, severely taxing the capabilities of web servers. Thus it is common,for multiple servers to run a single site. In our work, we use a novel network feature known as RDMA to vastly improve performance,and scalabil- ity of a single server. Using an unmodified Apache web server with a dynamic module to enable iWARP (RDMA over TCP), we can handle more clients with lower CPU utilization, and higher throughput.
