Question with running the optimization using cloud agents

 

Hi

So as the topic says, there are 6 in the cloud list, but when i try to run FAST, only 1 of the cloud in the list is processing and rest is on READY but not using is that normal?

do i have to run it on SLOW for them to all work at the same time? but it will cost a lot more?

please help me understand how it works, thanks~
