jjlharrison opened a new issue, #1331: URL: https://github.com/apache/maven-mvnd/issues/1331
### Affected version 1.0.2 and 2.0.0-rc-3 ### Bug description `mvnd` is very slow to start for me. Once the build has started it seems quicker than a normal `mvn` build, but with with slow start, overall it's much slower. Could this somehow be a problem with my configuration?  ``` $ ./mvn-benchmark.sh === Testing mvnd versions === --- mvnd@1.0.0 --- MVND_HOME=/Users/jjlharrison/.sdkman/candidates/mvnd/1.0.0 >>> mvnd --version Apache Maven Daemon (mvnd) 1.0.0 darwin-aarch64 native client (0cb7cbcbed6fad010b14dcd05acdc0a59685d88d) Terminal: org.jline.terminal.impl.PosixSysTerminal with pty org.jline.terminal.impl.jni.osx.OsXNativePty Apache Maven 3.9.8 (36645f6c9b5079805ea5009217e36f2cffd34256) Maven home: /Users/jjlharrison/.sdkman/candidates/mvnd/1.0.0/mvn Java version: 24, vendor: Eclipse Adoptium, runtime: /Users/jjlharrison/.sdkman/candidates/java/24-tem Default locale: en_GB, platform encoding: UTF-8 OS name: "mac os x", version: "15.5", arch: "aarch64", family: "mac" Warm-up run (not timed): Measuring mvnd compile for 5 runs under version 1.0.0...
