Novell and Ximian Novell plans an October launch for its Suse Linux Enterprise Real-Time product, an operating system geared for Wall Street traders and others who watch every microsecond of the clock. Novell plans to announce the product at the Gartner Symposium/ITxpo on Oct. 9, said Justin Steinman, Novell's director of marketing for Linux and open-platform solutions. Novell will share the stage with Concurrent Computer, which did much of the engineering work behind the real-time version that Novell will market, he added.

benefits of RT linux for server tasks?

I wonder if (soft) real-time scheduling is useful for common server tasks?

I guess for throughput oriented tasks such as serving complex dynamic pages then RT may not be so useful - in fact RT scheduling tends to degrade throughput tasks.

However, consider high volumes of small transactions - such as high use DNS or RADIUS proxy servers - or even highly web caches. Here there isn't too much computation to do and each transaction isn't pushing significant data around - perhaps RT can help improve the response rates - not by speeding them up (that's not what RT is about) but by reducing the variance in response times, by reducing the jitter. This has at least one useful benefit - more reliable capacity planning.

Any other ideas how RT OSes can help in common server tasks?
