We configure every new Linux KVM or Dedicated VDS game node using this four-step FragNode deployment checklist before opening public whitelist slots.
Open your local terminal with Ctrl+Alt+T, run mtr -rwc 50 against the vendor Singapore, Tokyo, Frankfurt, or US Looking Glass IP during evening hours, and inspect hop loss. Ctrl+Alt+T -> 0.0% Loss
Allow only gameplay UDP/TCP ports through UFW, bind MariaDB 3306 strictly to 127.0.0.1, and tunnel txAdmin 40120 or Rust RCON 28016 over SSH key authentication. ufw status: active
On a 16 GB DDR5 host, cap Java heap at -Xms12G -Xmx12G with Java 21 Generational ZGC so 4 GB stays free for Metaspace, Netty sockets, and Linux NVMe pagecache.
Schedule 6-hour rolling zstd snapshots of world directories, Level.sav files, and SQL dumps inside CubeCoders AMP or cron before applying SteamCMD or modpack updates.
Explore individual FragNode game server blueprints for per-slot RAM tables, startup flag snippets, and official developer wiki citations.
FragNode models Minecraft 1.21 PaperMC, Fabric, and 250-mod NeoForge packs by separating JVM heap (-Xms/-Xmx) from Linux kernel pagecache, Metaspace, and Netty off-heap network buffers so guilds hold a steady 50 ms tick budget (20.0 TPS).
FragNode sizes Cfx.re FXServer deployments by accounting for OneSync Infinity entity state replication, PMA-Voice audio routing, custom MLO/vehicle streaming assets, and local MariaDB InnoDB buffer pools on isolated VDS cores.
Pocketpair official requirements specify 16 GB minimum and 32 GB recommended RAM for Palworld dedicated servers because Unreal Engine 5 keeps explored world-partition cells and active guild-base Pal AI workers resident in memory.
Facepunch procedural maps generate 150,000 to 300,000+ Unity physics colliders at boot, meaning a 4250 worldsize wipe server with Carbon or uMod/Oxide plugins demands isolated 32 GB to 64 GB DDR5 memory, high single-core clock speeds, and inline RakNet UDP scrubbing.
Valve Source 2 dedicated servers require modest RAM (4 GB to 8 GB per match instance) alongside 60+ GB of fast NVMe storage and high single-thread CPU clock speeds (3.5 GHz+) so volumetric smoke grenades never push server frametimes past the sub-tick budget.
Official ARK: Survival Ascended dedicated server documentation warns that a single Unreal Engine 5 map instance claims 13.5 GB to 16 GB+ of RAM at idle startup before CurseForge crossplay mods, dino AI pathfinding, or megabase structures load.
Iron Gate Valheim dedicated servers persist terrain modifications and relay zone state across UDP ports 2456–2457, requiring 6 GB to 12 GB of host RAM for modded BepInEx worlds plus uncapped 256 KB/s network send buffers for large stone fortresses.
Enshrouded streams destructible voxel terrain chunks and independent Shroud timers per separated party, meaning 16 Flameborn split across four distant biomes demand fast NVMe decompression and 16 GB to 32 GB of isolated DDR5 memory.
We publish every constant behind our 4-zone sizing engine — from per-mod heap multipliers to OpenJDK 21 ZGC thresholds and 2026-11-12 vendor tier snapping — inside the FragNode methodology guide.
FragNode sums four physical zones: (1) Linux kernel, pagecache, and AMP/SSH daemon reserve (1.5–2.5 GB), (2) idle server binary footprint documented by the game developer (3.0–13.5 GB), (3) linear modpack/plugin/MLO heap (0–300 mods), and (4) concurrent player slots multiplied by an 8% spike buffer, then snaps upward to commercial DDR5 tiers.
OpenJDK 21 allocates Metaspace, thread stacks, JIT code cache, and native Netty network buffers outside the Java heap while Linux caches region files in RAM; setting -Xmx equal to 100% of VPS RAM triggers Linux OOM-Killer crashes during raids.
Because residential fiber peering and subsea cable maintenance shift dynamically, FragNode advises running mtr -rwc 50 against each vendor official Looking Glass IP during peak evening play hours (20:00–23:00 local time) before purchasing.
