Hi, > already running on high heap space (up to 10GB) I wouldn't say that 10GB is a high heap usage, so, it shouldn't be a problem.

More likely running multiple Ignite nodes on one machine with HDD will be a bottleneck for application - these nodes will compete for the I/O resources. Why did you decide to choose this architecture? Did you consider running an Ignite cluster separately from application and just having client nodes embedded in the application? What do you use there at the moment? Evgenii -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
