After nearly twenty years, Java has a new just-in-time (JIT) compiler, and it is only available in Azul Platform Prime. Azul Systems built the Falcon JIT compiler to ensure that Java developers and Java-based businesses can extract maximum performance from today’s server hardware.
The Falcon JIT compiler is fully integrated with Azul’s pauseless garbage collection technology as well as our ReadyNow technology, which solves Java’s warm-up problems in latency-sensitive applications.
The Falcon JIT compiler is based on technology from LLVM, the popular compiler infrastructure project with active involvement from leading universities and dozens of corporate contributors including Adobe, Apple, Google, NVIDIA, and Intel.
Today LLVM is used in a variety of programming languages and frameworks outside Java and the JVM, including newer platforms like Swift and Rust as well as many others including C/C++, Objective-C, Swift, Clang, OpenCL, CUDA and many more.
LLVM is considered the state-of-the-art in compiler technology, and the LLVM community is continually incorporating new optimization techniques and support for new processor instruction sets and hardware platforms.
The performance advantages for Java workloads when running with Azul Platform Prime’s new Falcon JIT compiler have significant business benefits:
Falcon has been shipping with Azul Platform Prime for several years. Starting version 17.03, Falcon became the default JIT compiler for Azul Platform Prime, replacing the legacy C2 compiler.
Yes.
Yes, C2 can be used by specifying a flag at JVM startup.
No.
Falcon works with applications built using any JDK version since Java SE 7/OpenJDK 7.
