Systems and methods are provided for zero buffer copying, where such a system includes one or more high performance computing systems, each including one or more processors and a high performance memory. The system further includes a user space that includes a Java virtual machine (JVM) and one or more application server instances; and a plurality of byte buffers accesible to the JVM and the one or more application server instances. When a request is received by a first application server instance data associated with the request is stored in a heap space associated with the JVM, and the JVM pins the portion of the heap space where the data is stored. The data is pushed to a first byte buffer where it is accessed by the first application server instance. A response is generated by the first application server using the data, and sent by the first application server.
