Over the past few months, several large organisations have asked us to resolve severe Dynamics 365 performance issues across Microsoft Dynamics 365 and legacy Dynamics AX environments. Using a tailored performance troubleshooting approach, we delivered measurable improvements in Dynamics ERP response times and batch runtimes—see our clients for examples.
If you’re unsure whether Dynamics is performing as it should, start by validating whether your environment is operating at its full potential. That’s where a structured Performance Troubleshooting Assessment helps: it identifies bottlenecks, isolates root causes, and prioritises fixes to restore performance quickly—see Performance Troubleshooting scenario for the approach.
In this article, we share practical performance troubleshooting lessons from client engagements across Dynamics 365 Finance & Operations and Dynamics AX—see Dynamics 365 for Finance and Operations for context on the platform.
Challenge 1: slow transportation planning
In one case, a commodities manufacturer running Microsoft Dynamics AX 2012 R3 saw severe slowness in the Transportation Planning form.
Following a targeted performance assessment, GO ERP implemented specific optimisations that reduced runtime by 95%—from 4.5 minutes to 15 seconds.
Why this matters: when planning tools lag, planners work around the system, decisions slow down, and execution performance (and customer promise) suffers.
Challenge 2: customisations that slowed the system
A distribution and retail organisation with more than 100 active ERP users reported persistent performance degradation—classic Dynamics 365 performance symptoms when volume meets inefficient patterns.
After an in-depth assessment, we found the main drivers were high-volume data processing combined with unoptimised customisations and inefficient query patterns.
GO ERP implemented a set of targeted fixes across code, database performance, and configuration.
In several high-impact processes, runtimes dropped from minutes to seconds—an improvement of more than 100× in the worst-affected scenarios. Across the impacted workflows, the runtime reduction translated into significant time saved each day across the user base.
Why this matters: when daily operations speed up, teams spend less time waiting, reworking, or firefighting—and more time executing.
What these examples show
These two examples show why Dynamics 365 performance troubleshooting is critical to daily operational throughput and user productivity. It also reduces operational cost, improves reliability, and protects service levels.
The most common causes of poor Dynamics ERP performance
Based on the performance assessments we’ve delivered, the biggest contributors to dynamics ax performance slowdowns (and similar Dynamics 365/AX issues) are:
- too many or poorly designed customisations,
- inefficient implementations (especially heavy forms, reports, and batch jobs),
- large data volumes without the right indexing, archiving, or query design.
In practice, dynamics ax 2012 performance issues often persist because teams treat symptoms (a slow form) instead of the underlying drivers (query design, data growth, or code paths).

What you get from a Performance Troubleshooting Assessment
Whether you’re already live on Dynamics 365 or still implementing, GO ERP offers a structured Performance Troubleshooting Assessment designed to surface bottlenecks and prioritise the fixes that deliver the fastest ROI.
Using proven tools and methods, we diagnose issues end-to-end—reviewing configuration, custom code, database performance, and infrastructure; validating with production-like datasets; and running peak load testing to pinpoint and quantify bottlenecks.
Where teams need fast stabilisation, the assessment is built to restore Dynamics 365 performance without guesswork—by isolating the bottleneck, proving it with realistic load, and prioritising the fixes that move the needle first.
For legacy estates, we apply the same discipline to dynamics ax 2012 performance: validate the workload, confirm the bottleneck, and fix what’s actually driving the runtime.
