I have about 200 servers in my hosts file. I can ssh to those servers without entering a password. ssh and no errors or trouble. When i attempt to run a simple Ad Hoc uptime command more that 50% of the servers show up as UNREACHABLE. Are there any setting I can use to improve this? Salt uses --async to improve response rates. Does ansible have any command line flags that are similar?
