# The JVM maximum is 8 PGC threads and 1/4 of that for ConcGC.
# Machines with > 10 cores may need additional threads. Increase to <= full cores.
# For systems with > 8 cores, the default ParallelGCThreads is 5/8 the number of logical cores.
# Otherwise equal to the number of cores when 8 or less.
# Machines with > 10 cores should try setting these to <= full cores.

# By default, ConcGCThreads is 1/4 of ParallelGCThreads.
# Setting both to the same value can reduce STW durations.
