HI Gianluca Removing this -XX:+AlwaysPreTouch did not help us at all, it took the same time with or without this. But I observed without this was, OS has not allocated entire heap memory we have given as JVM options, we were giving 200G as heap for ignite node, so when we execute top command, Ignite node used to use 250GB odd. Now after removing AlwaysPreTouch, ignite node use only 50G (around).
Other than, activation time remains same with or without AlwaysPreTouch. Thanks Naveen -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
