Standalone CEX Hummingbot containers run inside ~0.90 GB RAM, but full Hummingbot V2 stacks (EMQX MQTT broker + Backend API + Dashboard + Node.js DEX Gateway for Uniswap/Jupiter) push baseline memory past 5.5 GB. On BotFoundry, we pair 8–16 GB DDR5 tiers with 3.5GHz+ high-clock cores and kernel TCP keep-alive tuning.

| Concurrency Scale | vCPU | DDR5 RAM | OS / Runtime | /dev/shm & Watchdog Guard | Public Tier Match (2026-11-12) |
|---|---|---|---|---|---|
| 1–2 Standalone CEX Bots | 2 vCPU 3.5GHz+ HF | 4 GB DDR5 | Ubuntu 24.04 Headless | tcp_slow_start=0 + chrony |
Vultr HF 4GB ($24/mo) |
| 4–8 V2 Strategy Bots | 3–4 vCPU 3.5GHz+ HF | 8 GB DDR5 | Ubuntu 24.04 Docker | EMQX Cap + BBR Queue |
Vultr HF 8GB ($48/mo) |
| V2 + DEX Gateway + Dashboard | 6 Dedicated VDS | 16 GB DDR5 | Ubuntu 24.04 Docker | cpuset Pin + Node MaxOld |
UltaHost VDS 16GB / Vultr HF 16GB |
| Multi-Venue Desk (20+ Bots) | 8–12 Dedicated VDS | 32 GB ECC | Ubuntu 24.04 Tuned NIC | 16MB Socket Buffers + VDS |

net.core.wmem_max = 16777216During quiet market intervals, default Linux kernels shrink the TCP congestion window on idle HTTP/2 keep-alive connections. Setting net.ipv4.tcp_slow_start_after_idle = 0 ensures burst cancel-replace payloads transmit immediately at full socket window capacity.
Adding the TypeScript Hummingbot Gateway container (EVM/Solana SDKs), EMQX message broker, and Streamlit UI introduces four separate runtimes (Python, Erlang, Node.js, Postgres/SQLite) — making 8 GB tight and 16 GB DDR5 our clean operational baseline.
Pinning each Hummingbot Docker container to dedicated vCPU threads on a 6-core or 8-core UltaHost VDS prevents Python garbage collection in one strategy from stalling Cython orderbook parsing in another.
Each Hummingbot instance processes L2 orderbook diffs on a single-threaded asyncio/Cython event loop, so higher per-core clock frequency directly accelerates local state updates.
Encrypt Gateway keystores with a strong passphrase, fund isolated hot wallets with capped per-bot capital, disable SSH password login (Ed25519 keys only), and block all inbound ports via UFW.
Yes for up to 3–4 CEX-only bots without heavy historical backtesting; if you add DEX Gateway connectors or run 8+ strategies, step up to 16 GB RAM.
