Unlocking the Bottleneck: Why LLMs Slow Down
In every production system, your language model (LLM) is the performance bottleneck. Here’s why:
- Inefficient Architecture: While transformers are optimized for training, they falter during inference. Their sequential generation process is the root cause of increased latency.
- Attention Mechanism Pitfalls: The parallel training efficiency becomes a liability with memory constraints during generation. As the context grows, computation costs skyrocket.
- State vs. Stateless: The paradox unfolds: transformers are stateless but require growing contextual state to generate coherent responses.
Key Insights:
- Memory Bandwidth: With modern GPUs, moving data outpaces computation speed. This “memory wall” hinders performance during LLM inference.
- Future Optimizations: Understanding these bottlenecks paves the way for innovative solutions, including quantization and smarter caching strategies.
