Welcome to the home of the C++ Performance Benchmark suite
The benchmarks and web site are maintained by Chris Cox.
Primary Goals
- To help compiler vendors identify places where they may be able to improve
the performance of the code they generate.
- To help developers understand the performance impact of using different
data types, operations, and C++ langugage features with their
target compilers and OSes.
Secondary Goals
- To take performance problems found in real world code and turn them
into benchmarks for compiler vendors and other developers to learn from.
- Keep the benchmark code and build environment portable to as many compilers and OSes as possible.
- Not to use specialized optimization flags per test.
- December 8, 2008 - second public release
-
The benchmark code can be downloaded from C++Benchmarks.zip,
and release notes can be found on our Wiki.
I appreciate any help you can provide to improve the portability of the benchmark code.
- May 5, 2008 - first public release
-
The first public release identified a few more portability issues, which were fixed a few days later.
Multiple compiler writers identified and fixed bugs in their code based on the benchmarks.
- April 2008 - preview release sent to select compiler vendors
-
The first release outside Adobe: to get feedback on content, style, and issues found with certain compilers.
So far I have received replies from 3 vendors,
and 2 of them have found and fixed significant bugs based on the benchmark code.
