OrbitDock Memory Profiling

Overview

Capture reproducible OrbitDock memory artifacts from the command line, then map hotspots back to likely UI or rendering causes.

Workflow

Identify the target process.
Capture baseline snapshots.
Reproduce the issue.
Capture post-repro snapshots.
Compare outputs and form hypotheses.

Prefer using scripts/capture_memory_profile.sh for consistency.

Run The Script

Run a full capture for the latest OrbitDock process:

scripts/capture_memory_profile.sh

Run a targeted capture:

scripts/capture_memory_profile.sh \
  --pid 9718 \
  --sample-seconds 5 \
  --trace-seconds 10 \
  --out-dir /tmp/orbitdock-profile

Manual Commands

Use these directly when you need finer control:

pgrep -lf OrbitDock
ps -o pid,ppid,rss,vsz,%mem,etime,command -p <PID>
vmmap -summary <PID>
sample <PID> 5 1
xctrace record --template 'Allocations' --attach <PID> --time-limit 10s --output /tmp/orbitdock-alloc.trace
xctrace export --input /tmp/orbitdock-alloc.trace --toc
