VB6 Performance Optimisation

Address slow, fragile, or scaling‑limited VB6 applications with focused performance analysis and optimisation.

Slow, unresponsive, or fragile VB6 applications can be as damaging as outright failures. This service focuses on understanding and improving the performance characteristics of your system so it can handle current and future load with confidence.

Who this is for

  • Organisations experiencing slow screens, timeouts, or long‑running batch processes.
  • Systems that struggle under peak load or after growth in data or users.
  • Teams that have tried ad‑hoc fixes without systematic analysis.
  • Environments where performance issues have direct financial or operational impact.

Problems this service addresses

  • Poor user experience due to slow operations.
  • Timeouts and failures under load.
  • Inefficient queries, data access patterns, or algorithms.
  • Performance issues that are poorly understood and hard to reproduce.

Benefits and outcomes

Faster applications

Improved responsiveness for users and more predictable batch processing.

Reduced risk

Fewer timeouts and failures under load, reducing operational and reputational risk.

Better insight

Clear understanding of where performance bottlenecks really are and how to monitor them.

Approach

1. Profiling and measurement

We start by measuring, not guessing: profiling key operations, capturing timings, and identifying hotspots.

2. Bottleneck analysis

We analyse where time is spent: in VB6 code, database, network, or external services. This often reveals surprising bottlenecks.

3. Targeted optimisation

We implement focused changes: query tuning, caching strategies, algorithm improvements, or architectural adjustments where feasible.

4. Validation and recommendations

We validate improvements against baseline measurements and provide guidance on monitoring and future architecture.

Deliverables

  • Performance baseline report with key metrics and hotspots.
  • Summary of optimisation changes and their measured impact.
  • Recommendations for ongoing monitoring and future architecture.
