Quick Take
The study introduces a temporal semantic cache and workflow optimizations for AssetOpsBench, achieving a 1.67x speedup and 40% latency reduction in industrial asset operations. The temporal-cache benchmark demonstrated a remarkable 30.6x speedup on cache hits, highlighting the limitations of existing LLM caching techniques in parameter-rich queries.
Key Points
- MCP workflow optimizations led to a 1.67x speedup in execution.
- Median end-to-end latency reduced by approximately 40%.
- Temporal-cache benchmark achieved a 30.6x speedup on cache hits.
- Existing LLM caching techniques fail with time-sensitive industrial queries.
- Study provides critical insights into caching choices and evaluation correctness.

We evaluate this problem on AssetOpsBench (AOB), an industrial agent benchmark whose plan-execute pipeline exposes repeated overhead from tool discovery, LLM planning, MCP tool execution, and final summarization. Existing LLM caching techniques such as KV-cache reuse and embedding-based semantic caching were designed for chatbot serving and break down when output validity depends on time, asset, or sensor parameters. We propose two complementary optimization layers for AOB plan-execute pipelines: a temporal semantic cache and a set of MCP workflow optimizations combining disk-backed tool-discovery caching and dependency-aware parallel step execution. MCP workflow optimizations corresponded to a 1.67x speedup and reduced median end-to-end latency by about 40.0% while the temporal-cache benchmark achieved a median of 30.6x speedup on cache hits. Beyond the speedup, our results expose a concrete failure mode of pure semantic caching for parameter-rich industrial queries, providing a critical analysis of how caching choices interact with evaluation correctness in MCP-backed agent benchmarks.

Procedural Memory Distillation (PMD) enhances reinforcement learning by converting cross-episode signals into reusable memory, improving Qwen3-8B and OLMo3-Instruct-7B models by 3.8-5.5% on SCIKNOWEVAL and 7.9-13.6% on . The co-evolution of policy and memory allows for more effective self-supervision, demonstrating significant performance gains when both components are active.
