# -XX:+UseParallelGC throughput-oriented GC (better than G1 for batch workloads)

# -XX:+UseCompactObjectHeaders 64-bit object headers instead of 128-bit (JEP 450, JDK 24+)
|

# note: incompatible with -Xmx31G (compressed oops limit shifts to ~29G)
|
|
# -XX:+AlwaysPreTouch pre-fault heap pages at startup to avoid page faults later
|
|
# -XX:+EagerJVMCI initialize Graal JIT at startup for faster warmup (only with GraalVM)
