Why Choose Excelsior as My Java Consultant?
Because we literally know the Java technology inside out.
Excelsior is one of just a few Oracle Java SE Licensees out there. Our engineers went through every page of the JVM spec while working on Excelsior JET, our proprietary Java SE 8 implementation, and numerous JVM porting and optimization projects. They know how the core parts of the Java technology work, how to make them play well together, and how to tune them for optimal performance and throughput.
If the success of your project depends on understanding of the core Java concepts, features, and APIs — memory management, synchronization, collections, threading, networking, — to the finest level of detail on knowing their performance, scalability, and memory utilization characteristics, and so on, look no further.
