Java / GraalVM Interview questions
What are the benefits of using GraalVM Native Image?
Native Image's biggest wins show up in a handful of measurable areas compared to running the same app on a standard JVM.
| Benefit | Typical Impact |
| Startup time | Milliseconds instead of hundreds of milliseconds to seconds |
| Memory footprint | Lower resident memory, no JIT/interpreter data structures at runtime |
| Packaging | Single self-contained binary, no JVM install required on the target host |
| Predictability | Peak performance from the first request, no warm-up curve |
These benefits matter most for short-lived processes - CLI tools, serverless functions, and containers that need to scale up and down quickly - where JVM startup and warm-up cost would otherwise dominate the total run time.
Native Image mainly benefits which type of workload?
A native executable typically requires which of the following on the target host?
