Typically one executor per CPU core works well. Some people do two executors per CPU core. The other issue you need to consider is your I/O performance.
From: jenkinsci-users@googlegroups.com [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Vanetta Floyd Sent: Monday, November 23, 2015 10:59 AM To: Jenkins Users Subject: Number of executors I would like to verify - a good rule of thumb for how many executors to set on each build node is relative to the number of processors the build server has. Example - Server A: Number of Processors = 4 # of Executors = 4 Is this a good rule, or should I be looking at other factors? I currently have 2 executors (because of performance) set on each build server and I am getting requests to increase the number of executors. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
