Performance Comparison between C ++, C # and Java

Original article http://www.tommti-systems.de/go.html? Http://www.tommti-systems.de/main-Dateien/reviews/languages/benchmarks.html

 

A very old articleArticleHowever, the results are enlightening and indicate the differences in the performance of several languages. However, the test versions are old, so only the previous section is excerpted.

C ++ is the fastest, but STL hashmaps is much slower. Memory footprint
C # very fast, but there are some problems in handling exceptions, matrix multiplication and loop nesting.
Java's hashmaps are the fastest, and exception handling is very powerful.
C ++ is the fastest, but Java and C # are much faster in development than C ++.
