FragNode Minecraft Modpack & PaperMC JVM Sizing Blueprint
FragNode rule: reserve 25% host RAM outside -Xmx for Linux off-heap safety.
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.
FragNode security rule: deny public TCP 40120 and tunnel txAdmin over SSH.
When sizing a 48-to-128 slot QBCore or ESX city, we budget 2 GB to 4 GB exclusively for MariaDB innodb_buffer_pool_size so inventory and garage SQL writes never trigger server thread hitch warnings (>150 ms). Based on public specs retrieved 2026-11-12, FragNode maps persistent 64-slot cities to a 32 GB Dedicated VDS ($37.50/mo on UltaHost with published inline DDoS protection), while 16-to-32 slot whitelisted dev nodes fit 8 GB High Frequency 3.5 GHz+ instances on Vultr ($48.00/mo or hourly).
| Player Concurrency | Host RAM Tier | Heap Flag / CPU Target | Published Vendor Tier | Vendor Page |
|---|---|---|---|---|
| 16–32 Slots (Whitelist / Dev QBCore) | 8 GB – 12 GB | 3+ vCPU 3.5GHz+ NVMe |
Vultr HF 8 GB ($48.00/mo or Hourly) | Check Vultr High Frequency via FragNode |
| 48–64 Slots (QBCore + 180 Resources) | 32 GB VDS | 6 Dedicated VDS Cores |
UltaHost VDS 32 GB ($37.50/mo) | Check UltaHost Dedicated VDS via FragNode |
| 96–128 Slots (OneSync + PMA-Voice) | 64 GB VDS | 8 Dedicated VDS Cores |
UltaHost VDS 64 GB ($68.00/mo) | Check UltaHost Dedicated VDS via FragNode |
| 160+ Mega City (Split DB + Proxy) | 128 GB Bare-Metal | 16 Physical Cores |
UltaHost Bare-Metal 128 GB ($129.00/mo) | Check UltaHost Dedicated VDS via FragNode |

Keep MariaDB bound to 127.0.0.1 with innodb_buffer_pool_size = 4G on a 32 GB VDS so player inventory saves resolve in memory without disk I/O stalls.
Compress addon vehicle .ytd texture dictionaries below 16 MB per asset to prevent client VRAM exhaustion and 1 Gbps NIC egress saturation.
Block public access to TCP port 40120 via UFW and reach the txAdmin web dashboard strictly through an authenticated SSH local port forward or WireGuard tunnel.
We pre-linked this blueprint to our interactive FragNode 4-zone workbench so you can drag player concurrency up to 200 slots or adjust active mods between 0 and 300 in real time.
Running Linux FXServer artifacts on Ubuntu 24.04 LTS saves ~1.8 GB of idle GUI memory compared to Windows Server and avoids monthly Windows licensing surcharges.
FragNode folds database and resource heap overhead directly into Zone 2 and Zone 3 so your MariaDB InnoDB pool does not compete with FXServer OneSync memory.
No. Standard free web proxies only handle TCP 80/443 traffic; FiveM game state runs over UDP 30120 and requires inline L3/L4/L7 UDP filtering at the VDS host.
FragNode rule: reserve 25% host RAM outside -Xmx for Linux off-heap safety.
FragNode warning: 8 GB VPS nodes suffer UE5 OOM restarts once 4+ guild bases automate mining.
FragNode wipe rule: set +gc.buffer 4096 on 32 GB+ VDS nodes to suppress Unity GC rubberbanding.
