Excelsior LLC is the First Russian Company to Join the Eclipse Foundation

Excelsior has joined the Eclipse Foundation as an Add-In Provider. It turned out there are no other members from Russia, even though a number of Eclipse contributors, committers, and even project leads are based here. (In fact, the lead of the DLTK project is based right in our city.) So we are proud to be the first Russian corporate member of the Eclipse Foundation.

One of the obligations of an Add-In Provider member is to make a commercial Eclipse-based offering in 12 months. Our offering will be a tool designed for developers of (commercial) Eclipse RCP applications. We plan to announce it and make a public beta available on August 1st, 2008, so stay tuned.

I kindly invite industry analysts and authors covering Eclipse RCP to contact me to receive information and get the beta download about one week before the official annoucement. My contact is at the bottom of

Java vs. C Benchmark: Excelsior JET 6.4 Scores an Equalizer

Thanks to the application performance improvements in Excelsior JET 6.4, a draw has been declared in the latest round of Java vs. C benchmarking conducted by Stefan Krause.

The C team: GCC 4.2.3, LLVM 2.3

The Java team: Sun JDK 6 Update 2 and 6, IBM JDK 5 and 6, Excelsior JET 6.0 and 6.4, Apache Harmony M6


The last diagram is an attempt to summarize the results. I decided to compute for each benchmark the ratio of each compiler/JVM to the fastest competitor and take the geometric average of those figures. The results back quite nicely my feeling about their performance.

Java vs. Benchmark Composite Score

Conclusion
* Unsurprisingly GCC is fastest.
* Surprisingly it is followed very, very closely by JET 6.4, which delivers the best java performance.
