Please, get informed on what real-time is before you comment (in general it is good idea to understand a concept before you place confident comments like yours).
Real-time has nothing to do with performance and everything to do with predictability and deadlines.
People are put off when they find out that real time versions of Java or Linux are actually slower than the regular ones. Until you think about it a little bit and if they were faster there would not be multiple versions.
Real-time versions of products are created because sometimes performance is achieved by means of stochastic processes or amortizing costs and you need to remove these optimizations to be able to support deadlines.
Real-time programming emphasizes ability to calculate how long an operation will take as more valuable than raw performance.
