80 implementations of the same set of requirements, created
different programmers in various languages, are compared
properties, such as run time, memory consumption, source
comment density, program structure, reliability, and the
effort required for writing them.
The results indicate that, for the given programming
``scripting languages'' (Perl, Python, Rexx, Tcl) are more
than conventional languages. In terms of run time and
consumption, they often turn out better than Java and not
much worse than
C or C++. In general, the differences between languages
tend to be
smaller than the typical differences due to different
the same language.
