Phoronix performed interesting benchmarking analyses to determine the efficiency of Java on Windows Vista and Ubuntu platform.The results were quite obvious ,Ubuntu won hands-down.
What follow are few major extracts from their experiments:
- Windows Vista Home Premium SP1 and Ubuntu 8.10 were used .
- Each OS was left to its default settings, including the use of the standard desktop effects.
- All tests were executed through the Phoronix Test Suite.In Windows they were manually run .
- In Sunflow Rendering System,the performance between Ubuntu Linux and Windows Vista was quite close and between the official Java
and OpenJDK build on Ubuntu Linux the results were very close.
- In Fast Fourier Transform (FFT) performance measure, Java on Ubuntu was about 30% faster than Windows Vista Premium.
- In The Successive Over Relaxation (SOR) performance measure , Java on Ubuntu was about 33% faster than with Microsoft Windows.
- In Monte Carlo performance measure , Ubuntu’s JVM was 3 times faster than what was tested on Windows Vista.
- In composite performance measure , the best performance was exhibited using Java on Ubuntu. There was over a 50% difference, that separated Windows Vista and Ubuntu 8.10.
- The j2dbench performance was significantly better on Windows Vista Premium, but that’s likely attributed to the Intel graphics stack on Linux having little in the way of performance optimizations.
