Introduction

Recent technological innovations, such as advanced language models (LLMs), promise to boost software performance. Yet, many software applications still exhibit significant slowdowns. Why does this happen, and how can we improve the situation?

User Expectations and Technological Evolution

With the rise of LLMs, one might expect a drastic improvement in software performance. In theory, these tools enable the creation of specialized solutions and specific optimizations. However, adopting these technologies doesn't necessarily guarantee faster software. According to a 2023 Stack Overflow survey, 55% of developers state that increased user expectations are a major challenge to maintaining performance.

Increasing Software Complexity

Modern software is increasingly complex, integrating advanced features and rich user interfaces. This complexity often comes at the cost of performance. For example, a JetBrains survey shows that 60% of developers consider code complexity a key factor affecting speed.

Economic and Decision-Making Factors

The adoption of new technologies often depends on costs and economic decisions. Logically, companies should invest in optimizations that are cheaper thanks to LLMs. However, the reality is different. A recent McKinsey study highlights that only 30% of companies actively invest in performance optimization.

Lack of Resources and Expertise

The lack of experienced developers in performance optimization is another factor. With a talent shortage in the field, companies struggle to find the right skills. In 2023, LinkedIn reported a 20% increase in demand for performance-specialized engineers.

Conclusion

Software slowness results from many factors, from increasing complexity to economic decisions and a lack of resources. To overcome these challenges, it's crucial to invest in tailored solutions and ensure teams possess the necessary skills.
