[quote="mlotfy, post:3, topic:3723"] parallel build for each package is supported by the toolchain itself and that is what OP is asking about [/quote] Correct. [quote="mlotfy, post:3, topic:3723"] but parallel build for more than one package is not yet supported by ament [/quote] `ament build` has an option `--parallel` which also processes packages in parallel. There are known race conditions though (https://github.com/ament/ament_tools/issues/1450). We still use the feature on ci.ros2.org to speed up the builds. There is no configuration option to specify a limit for the packages processed in parallel. --- [Visit Topic](https://discourse.ros.org/t/how-to-set-number-of-parallel-jobs-in-ros2-building/3723/4) or reply to this email to respond.
