Just tried the 4.0.0-rc-3 comparing with 3.9.9, it's 4x times slower (!) on a project of ~900 modules (700 of them are jar). Maven 3 builds it in 2m57s, while Maven 4 in 11m48s (reproducible, with all m2 caches). No build cache solutions enabled to compare pure build time. Project is nothing special, just java 17 + kotlin 2.1 compilation (no test execution). It fits into the same heap memory. The CPU cores load is about the same (but 4x longer). It seems that somewhere there is a huge overhead.
Were there other performance tests at scale? On Mon, May 26, 2025 at 4:48 PM Maarten Mulders <mthmuld...@apache.org> wrote: > Totally agree!
