    "In a recent study [1], Prechelt compared the relative performance of Java
    and C++ in terms of execution time and memory utilization. Unlike many
    benchmark studies, Prechelt compared multiple implementations of the same
    task by multiple programmers in order to control for the effects of
    differences in programmer skill. Prechelt concluded that, "as of JDK 1.2,
    Java programs are typically much slower than programs written in C or C++.
    They also consume much more memory."
    We have repeated Precheltís study using Lisp as the implementation
    language. Our results show that Lisp's performance is comparable to or
    better than C++ in terms of execution speed, with significantly lower
    variability which translates into reduced project risk. Furthermore,
    development time is significantly lower and less variable than either C++
    or Java. Memory consumption is comparable to Java. Lisp thus presents a
    viable alternative to Java for dynamic applications where performance is
    important. "
