Hire an MS Access Performance Expert Who Measures Before Bragging
Timer numbers on the slow query, row counts before/after, and honest callouts when WAN or 2GB limits—not “buy SSD” hand-waving.
- Opening one form pulls half the database through DLookup in Current.
- Nested queries five levels deep—Access materializes what SQL Server would laugh at.
- Everyone hits the BE over VPN like it is a LAN—physics disagrees.
Most Access slowness is join shape and index use—not mystical corruption. If nobody can name the slowest object, you are guessing with money.
- USA, UK, Canada
- Remote
- Source .accdb / .mdb
Same-business-day triage when you send Access/Office version, bitness, and time zone.
Scoped work on copies first—no “debug on live production” roulette.
Performance Symptoms That Are Actually Engineering
- Report preview blocks the UI; users think Access crashed.
- Combo boxes load whole tables without WHERE clauses.
- Cartesian products disguised as “we needed all combinations.”
- Pass-through used wrong—or not at all—when Jet is doing hopeless work.
- Temp tables and scratch queries never cleaned up—bloat and plan churn.
Performance Work I Do in Access
- Read execution plans the honest way: timer + row counts + Jet showplan habits where useful.
- Fix joins and criteria to match selective indexes.
- Split heavy aggregates to pass-through or staged queries when appropriate.
- Form event review: what runs per row vs per form open.
- FE packaging guidance when WAN latency dominates.
Why Performance Fixes Get Political
The “fast” developer machine hides O(n²) loops.
Nobody wants to own that one query everyone is afraid to touch.
Indexes feel free until write paths slow down—tradeoffs need naming.
What Faster Feels Like
- Interactive forms again on real data volumes.
- Reports that finish in the meeting, not after it.
- A short written list: what was slow, what changed, how to verify.
Performance Engagement Steps
- Identify top three slow paths with repro.
- Baseline timings; fix smallest highest-impact slice first.
- Re-test on same hardware/network—no moving goalposts.
Typical Performance Wins
- Minutes-to-seconds on report queries after join/index correction.
- Form load time cut by killing per-row IO in events.
- Clear “stop” when physics says migrate or cache—not more VBA.

Frequently asked questions
Performance hiring—honest limits and what I need to profile.
Can you guarantee sub-second everything?
No. I guarantee measured improvement on named objects or I say why not.
Do you need production access?
Prefer copy + telemetry. Production only when policy forces it—and read-only where possible.
Is SQL Server required?
Not always. Sometimes Access-side query fixes are enough. Sometimes the BE is the bottleneck—I tell you which.
What if the network is the problem?
Then the fix is architecture—cached reads, fewer round trips, or migration—not index fairy dust.
How fast to start?
With named slow query and file copy, triage same week.
