The proliferation of high-performance scalable servers has added a new level of complexity to networking and system performance. In this article, learn how to optimize your multi-node, high-performance Linux® system as it uses system board gigabit Ethernet adapters from 1 to 4 nodes. Take a look at problematic networking scalability situations and get tips on how to avoid the pitfalls.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
