There were some particular tests that were extremely slow on windows and macos. But also there were some fairly invasive improvements on build side related to this problem: * we switched to more efficient runners on pr/push (ubuntu24.04-arm) and only triggering the macos at night. * use default flags (C2 compiler disabled, number of cores detection), this had a very large impact. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
