Stack composer

Started from [TR]DeadLyLife pvp pve https://discord.gg/fd3KyQZqy9: the 10 mods it publishes to the Steam server browser (as of 2026-10-20), 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.

Your stack in load order, earliest first. Drag a row, or use the arrows, to reorder.

Stall risks

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 4 below.

Mods silencing mods
None

Across 20 server-side methods hooked by two or more mods.

Structural load
0.14% of a frame at 100 players

1.425 ms per second, all 8 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.

MissionServer.OnUpdate
every server frame
PVEZ then Community-Online-Tools then CF then vanilla
DayZGame.OnUpdate
every server frame
Community-Online-Tools then CF then vanilla
DayZGame.OnRPC
per event
PVEZ RPC send world scan then CF sometimes stops here then vanilla
PlayerBase.EEHitBy
per event
PVEZ then Community-Online-Tools then vanilla
PlayerBase.SetActions
per event
MuchCarKey then Community-Online-Tools then vanilla

Stall risks#

4 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.

Everything else#

All 20 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.

27 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.
