At startup, vLLM typically performs CUDA graph capture only for the decode phase, and has a more aggressive trimming strategy for the set of captured batch sizes, so its cold-start graph capture phase is often shorter than SGLang's.

UnverifiedBecause the prefill phase must handle variable-length inputs, it often needs to capture CUDA graphs separately for multiple sequence lengths, further amplifying the recording time.69% similarUnverifiedvLLM's FULL graphs mode records the entire forward computation as a CUDA Graph as much as possible.67% similarUnverifiedPagedAttention memory management, dynamic batching scheduling, and custom CUDA kernel calls targeting different hardware in vLLM are operations that are difficult to capture with fullgraph.66% similarUnverifiedOverlapped checkpoint staged loading allows checkpoint pages to be loaded in parallel from storage in stages during CUDA graph capture.64% similarUnverifiedCUDA Graph is a performance optimization technology introduced by NVIDIA in CUDA 10 that reduces CPU-GPU synchronization latency through a record-and-replay mechanism.62% similar
