Why did java have the reputation of being slow? [closed] http://stackoverflow.com/questions/2163411/why-did-java-have-the-reputation-of-being-slow code beat the equivalent in C by reasonable margins. The JIT compiler is smart about using L1 L2 cache . Ahead of time compiled.. real time to the specific CPU system they're running on. JIT provides some very efficient loop transformations this way... facts contributed to the Java is slow reputation Before JIT compilation Java 1.2 1.3 the language was only interpreted not..
http://stackoverflow.com/questions/299068/how-slow-are-java-exceptions even if no exceptions are thrown is enough to prevent the JIT compiler from optimizing the code properly thus slowing it down... this try block the try block will be ultra fast as the JIT can then actually treat a throw like a simple goto. It neither.. all within the same method method3 but this is a special JIT optimization I would not rely upon. And even when using this..
Why does the JVM still not support tail-call optimization? http://stackoverflow.com/questions/3616483/why-does-the-jvm-still-not-support-tail-call-optimization function to simple loop must be done dynamically by a JIT compiler. It then gives an example of Java code that won't transform... Instead we must rely on dynamic compilation by the JIT. Depending on the JVM the JIT may or may not do this. Then it.. dynamic compilation by the JIT. Depending on the JVM the JIT may or may not do this. Then it gives a test you can use to..
