Dashboards that load fast and don’t leak data

Why reports time out, how to keep dashboards fast, and how to avoid accidental data exposure.

If a dashboard is timing out, the fix is almost never “try a different chart.”

It’s usually filters that are too wide, report types that are doing too much, row formulas that are doing work over and over, or a security mismatch that makes people think the data is “wrong.”

This is the approach I use to get dashboards snappy and keep access honest.

Start with security (or you’ll debug the wrong problem)

Reports respect:

  • object perms
  • field-level security
  • record access (OWD/roles/sharing)
  • “View All”/“Modify All” (bypasses sharing)

Diagnostic:

  • run as Admin
  • run as a normal user
    Different counts = access/sharing issue, not filters.

Why reports get slow

1) weak default filters

“All time” datasets are expensive. Prefer:

  • last 90 days
  • current FY
  • this quarter

2) complex report types / cross filters

Cross filters and deep relationships help, but cost. If the metric needs complex logic reliably, consider:

  • reporting snapshots
  • summary objects (“facts tables”)

3) formulas everywhere

Row-level formulas are easy to overuse. If a metric is stable and high value, compute once (field/automation) rather than at runtime.

Dashboards: reduce load

  • limit components (6–10 is enough)
  • avoid high-cardinality groupings where possible
  • choose “run as viewer” vs “run as user” intentionally

Accidental data exposure patterns

  • folder sharing too broad
  • “Export Reports” permission assigned widely
  • “View All” used as a shortcut
  • sensitive fields scattered across unrelated permission sets

Checklist

Performance:

  • strong default date filter
  • minimal joins/cross filters
  • limited row formulas
  • dashboard component count reasonable

Security:

  • folder sharing least privilege
  • export controlled
  • tested as normal user
