## Infinispan Server Settings
|
|
|
|
| Category | Setting | Property | Default value |
|
|
|-------------|-------------------------------|-------------------------|-----------------------------------------------------------------------------------------|
|
|
| JVM | Memory settings | `infinispan.jvm.memory` | -Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -XX:+DisableExplicitGC |
|
|
|
|
## Docker settings
|
|
|
|
By default, there are 4 CPU cores allocated: core 0 for monitoring, core 1 for database (MariaDB), and cores 2 and 3 for Keycloak server.
|
|
Default memory limits for database and Keycloak server are 2g. The `cpuset` and `memlimit` parameters set here are set to `cpuset` and
|
|
`mem_limit` parameters of docker-compose configuration. See docker-compose documentation for meaning of the values. How to set the parameters
|
|
correctly depends on number of factors - number of cpu cores, NUMA, available memory etc., hence it is out of scope of this document.
