![]() You do not even have to be a Java developer! If other JVM languages are your cup of productivity, that is okay. GraalVM fits into your workflow, being a compatible JDK it not only runs the applications you are working on, but the Java tools that help you! GraalVM works in your debugger, works with your build tools, it works within your favourite IDE, you can migrate your continuous integration environment to it, run your issue tracker on it and all other Java services you are using. GraalVM can run Java applications offering better performance without code changes or any learning curve for developers. One of the best features of GraalVM is its compatibility with all the tools in the Java ecosystem. Quick start Equally excellent developer productivity Migrating services to GraalVM mostly consists of replacing the JDK downloads or base container images with the GraalVM based ones without code changes or needing to leverage new language features! To use GraalVM to speed up Java applications, build native executables with the Native Image feature, or incorporate libraries from other languages, you do not have to undergo complex migrations to the latest OpenJDK release. GraalVM includes a compatible JDK and currently offers downloads based on Java 8 or Java 11. GraalVM’s dedication to improving the Java ecosystem comes with support for those major versions which are the most popular. While the OpenJDK project moves forward with the 6-month release cadence, which offers time-based release model where features get in whenever they are ready, a large part of the Java ecosystem is still using Java 8 and Java 11 in production. Quick start Better performance with no code changes Chris Thalinger, Staff Software Engineer, Twitter Being able to see 8–11 percent performance improvements on the same hardware without having to change the underlying code is a once-in-a-lifetime event, leading to substantial cost savings and future flexibility for Twitter. With the efficiency of the GraalVM JIT compiler, Twitter is able to meet their throughput targets with fewer servers, resulting in significant savings. To keep costs down and performance up, Twitter relies on GraalVM to run core services like Tweet, Social, and News. Twitter is one of the most popular social media services in the world running a platform used by millions of users around the globe daily. Kurtis Bowman, Director of Architecture, Server Office of the CTO, Dell EMC Something to Tweet About Java workload analysis and SPECjbb®2015 benchmark improving max-jOPS results by almost 8%. Oracle GraalVM Enterprise Edition was the performance choice for our Dell EMC Servers. That is one less cloud server to pay for or one less datacenter server to buy and maintain. These goals are definitely laudable, and achieving them is easier with GraalVM, but the real value of these improvements is a reduction in the cost to run an application in production.įaster applications with lower resource requirements translate into fewer servers required to deliver a given service, and fewer servers means lower monthly cloud bills and lower capital and operating costs for on premises deployments.Įven with no reduction in resource requirements, with just a ~11% improvement in throughput, 9 servers can do what required 10 before. ![]() Higher application performance and lower CPU and memory usage are goals every developer strives for. OCI Monitoring Service Throughput (transaction per second) These improvements have significant benefits for a memory intensive service that routinely processes tens of millions of data points, ingests billions of metrics, and serves millions of requests coming from an ever growing collection of OCI service offerings.įigure 2. Oracle Cloud Infrastructureīy running the Oracle Cloud Infrastructure (OCI) Monitoring (telemetry) service on GraalVM Enterprise, a 10% transaction processing rate increase was achieved along with a 25% reduction in garbage collection times, a 17% reduction in GC pause times, and a 5% reduction CPU utilization. On the Renaissance benchmark suite, which “contains a range of modern workloads, comprising of various popular systems, frameworks and applications made for the JVM”, GraalVM Enterprise achieves a geomean speedup of 1.55x over OpenJDK 8 and similar results for OpenJDK 11. The size of the speedup depends on the type of workload. The end results are applications that run faster and consume fewer resources-reducing cloud and infrastructure costs. GraalVM’s high-performance JIT compiler generates optimized native machine code that runs faster, produces less garbage, and uses less CPU thanks to a battery of advanced compiler optimizations and aggressive and sophisticated inlining techniques.
