Openjdk profiler
The service is built to run on production server environments with virtually no overhead and enables development and devops teams to understand the production behaviour of applications. It does this by coupling a commercially tested and supported always-on JVM profiler with a back-end service for indexing and on-demand browser-based aggregation of the profiling data. Opsian’s Continuous Profiling service helps teams rapidly identify performance issues in production environments. If your organisation uses GraalVM with either of these technologies and would like to know more about our support for them please get in contact with us. Work to support Ahead-Of-Time compilation via native-image and other non-JVM languages is still on-going. This makes it substantially easier for teams to identify performance issues and proactively carry out performance work to remove scalability bottlenecks.Īs of now, Opsian supports GraalVM when run as a Java VM. Opsian’s Continuous Profiling gives development teams access to real-time performance profiling data from production server environments via browser-based reporting dashboards. It also aims to support other languages and runtimes such as Javascript, Ruby, Python and even LLVM bitcode all running within the same JVM. Notably, applications making heavy use of the Streams API can see significant increases in performance. It features aggressive inlining and other advanced optimisations such as partial escape analysis, which can substantially reduce the number of allocations in modular Java code. By replacing the existing C++-based compilers in the JVM (C1 and C2) with a Java-based compiler it aims to be more maintainable and extensible. GraalVM is primarily a Java VM and JDK based on HotSpot/OpenJDK with the JIT compiler implemented in Java. We’re pleased to announce that Opsian now supports Continuous Profiling on the GraalVM JVM- this means that GraalVM users now have access to the same always-on low-overhead performance data as users of OpenJDK-based builds.
