Hi, I would like to know whether is java too slow running on old hardware like 800mhz processors, based on real experience? Also if any one can post articles regarding this topic, it'll be so useful.
There is nothing magical about Java that would make it slower than any other technology on old hardware provided the system has enough memory and the Java version is correct for the operating system.
I do JetSpeed2 portlet development on a Dell Latitude laption with a 800MHz processor and 512 megs of RAM. That's development! As for running? No problem.
I am not aware of anything like this. If your hardware is slow and cant keep up with the needs of any language, all applications are bound to run slow.
"I would like to know whether is java too slow running on old hardware..."
That depends on what you mean by "too slow". Also, Java is just the programming language and the Java runtime environment. Whether a program written in Java is slow or not depends for a great deal on that particular program, and not on the fact that it's a Java program.
