— Most event loops will be short


A normal process will do some work, then go into an event loop, or even call EVENT_WAIT on the dispatcher

— Huh

— But won't the slow jobs run eventually though?

— Yes, giving small event loops time to run

— If an event fires something, then a short job could become a long job on that cycle, which means on the next cycle it runs later

— I see

— Which means, continually, the processes that have the smallest load on the system will always run first

— So processes will be rewarded by being efficient

— Exactly

— Since it is cooperative, a developer can directly implement efficiency by splitting their application up into units of work, yield ing to the dispatcher frequently

— I will also add HRRN which apparently also gives priority to procs that have to wait a long time
