# Linux 102

Six complete null-RHI Unreal traces on `55e20f4`, with the L97 low-priority tile settings and tick logging enabled. Unreal was launched as `taskset -c 0-11 timeout 1740s`; it had no address-space cap. No build was needed: the VFHost plugin source matches this checkout and its module binary postdates the source.

| Stratum | First admission | LOD0–2 settled | From admission | `UWorld::Tick` p99 / worst max | `AVoxelWorld::Tick` p99 / worst max | EndPhysics gap max |
|
||
|---|---:|---:|---:|---:|---:|---:|
|
||
| FI | 0.385 s (0.382–0.388) | 1.943 s (1.922–1.951) | 1.555 s (1.541–1.566) | 4.8–6.6 / 6.7 ms | 4.2–4.8 / 5.1 ms | 1 ms |
|
||
| SW | 0.415 s (0.414–0.417) | 1.706 s (1.706–1.713) | 1.292 s (1.289–1.298) | 8.5–10.0 / 12.0 ms | 7.9–9.4 / 11.3 ms | 2 ms |
|
||
|
||
Times are medians across three complete runs, with ranges in parentheses. Tick p99 columns show the three-run range; max is the worst per-run maximum.
|
||
|
||
Compared with L97, median settle from first admission was 2.109 s / 21 ms max `UWorld::Tick` for FI and 1.316 s / 11 ms for SW. L102 measured 1.555 s / 6.7 ms for FI and 1.292 s / 12.0 ms for SW. The largest EndPhysics gap fell from 16 ms / 7 ms to 1 ms / 2 ms.
|
||
|
||
Peak Unreal RSS (`VmHWM`) was 2,378.7 MiB (2.32 GiB): FI runs were 2,370.5–2,378.7 MiB and SW runs 2,275.3–2,295.6 MiB. There was no L97-era executable or RSS record available; a separate old host/plugin build would be needed, so the memory delta is unknown.
|
||
|
||
Failed L102 runs: none. All six exited 0 and settled LOD0–2. Logs and per-run summaries are in `Saved/Linux/l102/unreal-arrival/`. No installs, commits, pushes, or stashes.
