Java 25's new CPU-Time Profiler
SMRTR summary
Java 25's new CPU-time profiler solves key limitations of the existing execution-time profiler by measuring actual CPU usage rather than wall-clock time. The experimental feature helps developers identify methods consuming most CPU cycles—particularly useful for improving throughput in I/O-heavy applications where CPU bottlenecks may be hidden in traditional profiles. Currently limited to Linux systems, it provides more accurate insights with detailed failed sample reporting.
