In the case above, the risk is that milano will always be chosen. When milano’s load is too high, it’ll fall back to the next machine, but then it means scheduling is wasting time always contacting machines in the same order, which goes against the strategy of ‘choose-build-machine’ in (guix scripts offload). Maybe acceptable when there are few machines, but otherwise not great. :-) Ludo’. ^ permalink raw reply [flat|nested] 2+ messages in thread
