Stack composer

Started from Mystery Test: the 12 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

3 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 3 below.

Mods silencing mods

None

Across 22 server-side methods hooked by two or more mods.

Structural load

0.32% of a frame at 100 players

3.248 ms per second, all 9 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.

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.

DayZGame.OnUpdate

every server frame

VPPAdminTools then CF then vanilla

PlayerBase.SetActions

per event

RedFalcon Flight System Heliz then Advanced Weapon Scopes then WindstridesClothingPack then VPPAdminTools then vanilla

DayZGame.OnRPC

per event

Building Fortifications then VPPAdminTools sometimes stops here then CF sometimes stops here then vanilla

CodeLock.SetActions

per event

MMG Base Storage then Building Fortifications then vanilla

Hacksaw.SetActions

per event

Code Lock then Building Fortifications then vanilla

SledgeHammer.SetActions

per event

RedFalcon Flight System Heliz then Building Fortifications then vanilla

Stall risks#

3 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.

VPPAdminTools

PlayerBase.CommandHandler

about 30× per player per second

Per-player, per-frame hook warning

VPPAdminTools.pbo::4_World\VPPAdminTools\Entities\PlayerBase.c:401

VPPAdminTools

SurvivorBase.EOnFrame

about 30× per player per second

Per-player, per-frame hook warning

VPPAdminTools.pbo::4_World\VPPAdminTools\Entities\SurvivorBase.c:42

VPPAdminTools

SurvivorBase.EOnPostFrame

Per-player, per-frame hook warning

Everything else#

All 22 server-side methods hooked by two or more mods

vanilla → earliest mod → … → latest mod (dispatch enters at the latest). ~~struck~~ = suppressed by a later chain break; ✂ = no super(); "(cond)" = super() only on some paths.

No cross-mod interaction is possible here; a ✂ still means vanilla's behaviour on that method is replaced.

21 methods on client-only classes are not shown: a dedicated server never runs them.

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.
