Abstract: “Due to the rapid increase in network services per network node, the need for high throughput infrastructure is growing. Throughput and latency are two important criteria that need to be considered while working on Real Time Embedded Systems. With the advent of Real Time Operating systems, low latency can be achieved, but sometimes at the cost of performance. The situation becomes complex if the system has a networking termination application in the user-space operating with the kernel space driver. The paper presents how changes in Real Time Linux impose complexity in a network application both in kernel and user space. This paper also discusses ideas to identify problems and fixes available using Linux debugging tools. This paper concludes by sharing performance improvement data achieved in a user space networking application”
