I have done some scaling experiments. on a AWS M3.large using mostly default JVM sizings I can get one of: * 60 JNLP slaves with 2 executors per node. I was able to get up to 60 concurrent builds of the "mock-load" plugin's type before the jenkins master system load goes above 5 and thus critically impacts the UI performance on an M3.large * 60 standard SSH slaves 2 executors per node. I was able to get up to 10-15 concurrent builds of the "mock-load" plugin's type before the jenkins master system load goes above 5 and thus critically impacts the UI performance on an M3.large * 60 of CloudBees Jenkins Enterprise NIO SSH Slaves, 2 executors per node. I was able to get up to 120 concurrent builds of the "mock-load" plugin's type. The jenkins master system load never went above 3. There was back-pressure on the remoting channels once there was more than 25 concurrent builds. The back pressure resulted in increased build times, however the UI remained performant throughout. > > TX! > > -- > You received this message because you are subscribed to the Google Groups > "Jenkins Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to jenkinsci-users+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
