# Performance suggestions for grid  (fix if possible)
# To disable, set -DIGNITE_PERFORMANCE_SUGGESTIONS_DISABLED=true

#       (add '-XX:MaxDirectMemorySize=<size>[g|G|m|M|k|K]' to JVM options)
#   ^-- Disable processing of calls to System.gc() (add '-XX:+DisableExplicitGC' to JVM options)
#   ^-- Speed up flushing of dirty pages by OS (alter vm.dirty_expire_centisecs parameter by setting to 500)
JVM_OPTS="-Xms1g -Xmx4g -XX:MaxDirectMemorySize=64g -XX:+DisableExplicitGC -server -XX:MaxMetaspaceSize=256m"
