EMBEDDED WORLD, Nuremberg and SUNNYVALE, Calif., – Azul Systems (Azul), the leader in Java runtime solutions, today announced the general availability of Checkpoint/Restore “C/R” functionality for Zulu Embedded builds of OpenJDK. Observed start time improvement with C/R ranges from up to 30% on the low end to over 10X faster at the high end, delivering startup times that meet even the toughest service levels.
C/R for Zulu Embedded is available at launch for the following processor architectures:
- 32-bit Arm® processors with soft floating point
- 32-bit Arm processors with hardware-enabled floating point
- 64-bit Arm processors
“Checkpoint/Restore is a powerful new technology that helps our customers deliver great startup performance using cost-effective and highly-efficient Arm devices,” said Gil Tene, Azul Systems co-founder and CTO. “In many device types, seconds and even milliseconds can matter at startup. Zulu Embedded with Checkpoint/Restore can provide a winning advantage to embedded project teams challenged by tough SLAs.”
