Stack composer

Started from ATOM | STALKER RP https://discord.gg/x36v7QHrXn: the 21 mods it publishes to the Steam server browser (as of 2026-10-19), put back into load order — servers publish the list last-loaded first. Mods loaded with -servermod= are never published, so they are not here; add them if you know them.

Stall risks

7 in hot hooks

File I/O on hot paths, timers created per event, and per-player-per-frame hooks across the stack. These can stall a frame regardless of the load figure. See all 7 below.

Mods silencing mods

None

Across 32 server-side methods hooked by two or more mods. 1 more on client-only UI classes, listed separately.

Structural load

0.51% of a frame at 100 players

5.055 ms per second, all 14 mods combined. Hook dispatch and timers only — not what the hooks do inside. Methodology.

Who silences whom#

A later-loaded mod overrides a method without super(), so the earlier mod's code on that method — and vanilla's — never runs. Whether that is a bug or the whole point of the mod is the author's call; this shows the structure, not intent.

✓ No server-side conflicts: every method two or more of these mods hook preserves super() end to end.

1 conflict on client-only classes (menus, HUD, notifications) — no server effect

NotificationSystem.GetNotificationData — CF silences Dabs Framework

Hot hooks shared across the stack#

The engine calls the last-loaded mod first; each super() hands on to the mod before it, ending at vanilla. Badges show what each mod's override calls inside — that body work, not the chain itself, is what costs frame time.

PlayerBase.CommandHandler

about 30× per player per second

SFP then VPPAdminTools RPC send then vanilla

DayZGame.OnUpdate

CF then VPPAdminTools then vanilla

DayZGame.OnRPC

CF sometimes stops here then Dabs Framework then VPPAdminTools sometimes stops here then vanilla

PlayerBase.OnRPC

SFP_anim_system then SFP sometimes stops here then VPPAdminTools then vanilla

PlayerBase.OnVariablesSynchronized

SFP_anim_system then SFP then VPPAdminTools then vanilla

PlayerBase.SetActions

SFP_anim_system then VPPAdminTools then vanilla

Stall risks#

7 places where one mod's code can hold up a frame by itself, whatever the load figure says. Each is a pattern found in the code, not a measurement: how much it costs depends on what the hook does inside. Most severe first, then in load order.

Per-player, per-frame hook. Runs for every player on every tick, so whatever it does inside is multiplied by the population.
Timer created inside a hot hook. Registers a timer each time the hook runs. Timers that are never cleaned up pile up in the queue the server walks every frame; the analysis cannot see the cleanup, so read the code.

Reading this page.

A conflict shows that code is skipped, not that an author made a mistake — overhaul mods replace systems on purpose. Long chains are cheap: one link costs about 25 ns per dispatch. What costs frame time is the work inside each hook, which is why the badges are there. Everything here comes from the mods' code alone; nothing was measured on a server. Methodology.
