Benchmarks: measuring CMUCL performance
|
There are lies, damned lies and benchmarks.
-- after Benjamin Disraeli
Here are the results of some performance benchmarking tests run on a
number of different Common Lisp implementations. The tests run include
- the well-known Gabriel benchmarks
- hashtable exercising
- READ-LINE exercising
- mathematical functions: factorial, fibonnaci, ackermann's number
- some bignum intensive code from Bruno Haible
- various aspects of CLOS: time taken to compile and execute DEFCLASS forms which create a class
hierarchy, instance creation time, time taken to compile and execute
DEFMETHOD forms, execution of method
combinations, both with and without :after methods.
- various operations on arrays, bitvectors and strings.
Except for the CLOS code, timings do not include compilation time. The
garbage collector is run before each test to try to make the timings more
repeatable. Remember that the only real benchmark is your application: this
code is only representative of real-life programs to a limited extent. For
certain targets, we assume that the times reported by GET-INTERNAL-RUN-TIME and GET-INTERNAL-REAL-TIME are accurate.
The code for these performance benchmarks can be downloaded from www.chez.com/emarsden/downloads.
Here is an example of the type of results you can obtain, for x86 and
SPARC platforms. To interpret these numbers: the number in the Reference
column is a number of seconds taken to execute that test. The other numbers
are the relative performance of that implementation, so for example a
number of 1.3 means 30% slower than the reference implementation. A number
of -1 means that the corresponding test was not run on that implementation,
either because it does not support the given feature (certain types of
method combination for CLISP, for instance), or because of implementation
limits (heap size limit on LispWorks Personal, for example).
