ERPNextCalc Sizing Methodology & Deterministic Formulas
ERPNextCalc computes Frappe v15 and ERPNext v15 RAM budgets deterministically from open architectural constants rather than opaque guesses.
All outputs from ERPNextCalc serve as engineering planning baselines; verify staging memory telemetry before cutting over production traffic.
ERPNextCalc Gunicorn & Python Bytecode Formula
ERPNextCalc calculates gunicorn_workers = (2 * vCPU) + 1 and multiplies each process by a 260 MB RSS baseline assuming --preload is active in Supervisor.
We recommend keeping worker counts strictly bound to vCPU cores so Python GIL contention and Linux context switching do not degrade Desk API latency.
ERPNextCalc Redis RQ & MariaDB 45% RAM Discipline
Background workers are budgeted separately by queue class: 512 MB per short worker, 768 MB per default worker, and 1,024 MB per long worker handling BOM explosions or bulk CSV imports.
On co-located hosts, our sizing formula caps MariaDB innodb_buffer_pool_size at 45% of physical RAM (for example, 7,372 MB on a 16 GB server) so Python workers retain safe burst headroom.
ERPNextCalc Public Vendor Pricing Snapshot (2026-11-12)
Infrastructure rates cited across ERPNextCalc reflect public pricing retrieved on 2026-11-12 from Hostinger, Vultr, UltaHost, InterServer, and ChemiCloud.
In our audit of per-seat ERP SaaS licensing ($25/seat/mo baseline), self-hosting on fixed VDS hardware eliminates linear seat tax as warehouse and shop-floor headcount grows.
