Beyond the general impression   that they are ``slow,'' however, little has been documented   about the performance of interpreters as a class of  applications.<p>  This paper examines interpreter performance by measuring and  analyzing interpreters from both software and hardware perspectives.  As examples, we measure the MIPSI, Java, Perl, and Tcl interpreters  running an array of micro and macro benchmarks on a DEC Alpha  platform.  Our measurements of these interpreters relate performance  to the complexity of the interpreter's virtual machine and  demonstrate that native runtime libraries can play a key role in  providing good performance.  From an architectural perspective, we  show that interpreter performance is primarily a function of the  interpreter itself and is relatively {\em independent} of the  application being interpreted.  We also demonstrate that high-level  interpreters' demands on processor resources are comparable  to those of other complex compiled programs, such as gcc.  We  conclude that interpreters, as a class of applications, do not  currently motivate special hardware support for increased  performance.<p><!WA0><a href="http://www.cs.washington.edu/homes/romer/rocky/InterpreterS+P.ps">Download postscript</a>.<br><hr><!WA1><a href="http://www.cs.washington.edu/homes/romer/rocky/index.html">Rocky home page</a>.</html></body>
