Introduction

BiSheng JDK is an open-source Huawei JDK distribution developed on OpenJDK. It runs on Kunpeng processors to offer acceleration features, including enhanced heap dump, JBooster, and JBolt. This document describes how to install the BiSheng JDK acceleration library and how to use these features.

• Enhanced heap dump masks sensitive information in heap dump files to protect data security and privacy.
• JBooster accelerates application startup, reduces CPU usage, speeds up elastic scaling, and cuts cloud application deployment costs.
• JBolt optimizes the code cache layout to reduce the iCache/iTLB miss rate and improve application performance.
• JProfileCache reduces the time to reach applications' TPS upper limit through ahead-of-time (AOT) compilation of hotspot methods.
• DynamicMaxHeap allows dynamic adjustment of the heap upper limit during application running.
