Minecraft Sunucu Flag Üreteci

Minecraft sunucun için optimize edilmiş JVM flag'leri üret. Sahada test edilmiş bir preset seç — Aikar's, MeowIce, Benchmarked G1/ZGC/Shenandoah, Hilltty, Obydux, Etil — ve doğrudan çalıştırılabilir start.sh, .bat, .command, Dockerfile, systemd ünitesi veya Pterodactyl egg al.

Java sürümü

Gelişmiş seçenekler

Başsız (--nogui)

Swing GUI olmadan başlatır. Proxy'ler için otomatik kapatılır.

Tam stack trace göster

-XX:-OmitStackTraceInFastThrow ekler; tekrarlanan exception'lar bile stack basar.

Otomatik yeniden başlatma

Script'i while/goto döngüsüyle sarar; sunucu çökerse yeniden başlar.

Script değişkenleri kullan

Script'in başına fileName= ve memory= değişkenleri yerleştirir, kolay düzenleme sağlar.

JVM overhead'i hesapla

İstenen miktarın altında bir -Xmx yerleştirir; off-heap belleğe yer bırakır.

Büyük sayfalar (HugeTLB)

-XX:+UseLargePages aktifleşir. Çekirdek + Java desteği gerekir.

Flag dökümü

Bellek

-Xms4096M
Initial heap size. Set equal to Xmx so the JVM doesn't grow on demand.
-Xmx4096M
Maximum heap size. Hard cap on the Java heap.

Preset flag'leri

-XX:+UseG1GC
Garbage-First collector. Best general-purpose GC for Paper-family servers.
-XX:+ParallelRefProcEnabled
Parallelises reference processing during GC pauses.
-XX:MaxGCPauseMillis=200
Soft target for GC pause time. G1 will trade throughput to stay under it.
-XX:+UnlockExperimentalVMOptions
Allows experimental tuning flags.
-XX:+DisableExplicitGC
Ignores System.gc() calls from plugins/mods.
-XX:+AlwaysPreTouch
Touches every heap page on startup. Slower boot, smoother runtime.
-XX:G1HeapWastePercent=5
Waste threshold before mixed GCs are triggered.
-XX:G1MixedGCCountTarget=4
Number of mixed GC cycles to drain old-generation garbage.
-XX:InitiatingHeapOccupancyPercent=15
Heap occupancy that triggers a concurrent GC cycle.
-XX:G1MixedGCLiveThresholdPercent=90
Live data threshold above which a region is skipped during mixed GC.
-XX:G1RSetUpdatingPauseTimePercent=5
Maximum pause time spent updating remembered sets.
-XX:SurvivorRatio=32
Eden:Survivor space ratio. 32 keeps short-lived objects from promoting too fast.
-XX:+PerfDisableSharedMem
Disables /tmp/hsperfdata files; avoids stalls on slow disks.
-XX:MaxTenuringThreshold=1
Promote survivor objects to old gen after N collections.
-Dusing.aikars.flags=https://mcflags.emc.gs
Marker constant Aikar's flags look for at startup.
-Daikars.new.flags=true
Enables Paper's tuned defaults that match these flags.
-XX:G1NewSizePercent=30
Minimum young generation as % of heap. Higher = better throughput, more pauses.
-XX:G1MaxNewSizePercent=40
Maximum young generation as % of heap.
-XX:G1HeapRegionSize=8M
G1 region granularity. 8M for ≤12 GB heaps, 16M above.
-XX:G1ReservePercent=20
Heap percentage kept as a reserve for evacuation failures.

Sistem / debug

-XX:-OmitStackTraceInFastThrow
Forces full stack traces, even for repeated exceptions.
