In the news and information industry, latency is not a technical metric — it is a business metric. The difference between capturing a breaking story in 30 seconds versus 3 minutes can mean the difference between being the source and being the echo. OpenClaw, deployed on Tencent Cloud Lighthouse, offers a powerful framework for building high-speed news capture and aggregation pipelines. But out of the box, you need to tune it. Here is how to squeeze maximum performance from your setup.
A typical OpenClaw news aggregation system has four stages, each with its own performance bottleneck:
The total latency is the sum of all four stages. Optimizing only one stage while ignoring the others leaves performance on the table.
The naive approach — polling sources sequentially — creates a linear scaling problem. If you monitor 50 RSS feeds with a 2-second timeout each, your best-case cycle time is already 100 seconds.
Solution: Configure your ingestion Skills to poll sources concurrently. OpenClaw's Skills architecture supports parallel execution. Structure your feeds into priority tiers:
Maintain persistent HTTP connections to frequently-polled sources. Creating a new TCP + TLS handshake for every request adds 100-300ms of unnecessary overhead. Most HTTP client libraries used in OpenClaw Skills support connection keep-alive by default — make sure it is not disabled.
Duplicate detection is computationally cheap but becomes expensive if you process the full article before checking. Implement a two-pass deduplication strategy:
Named Entity Recognition (NER) does not need to run through the LLM. Use lightweight, local NER models (spaCy, for instance) as a pre-processing step within your Skills. Reserve expensive LLM calls for tasks that genuinely require language understanding.
This is typically the biggest bottleneck. LLM inference is slow and expensive relative to other pipeline stages.
Instead of sending each article to the LLM individually, batch multiple articles into a single prompt where possible. Summarizing 5 articles in one call is significantly faster than making 5 separate calls, thanks to reduced round-trip overhead and more efficient GPU utilization.
Shorter prompts produce faster responses. Strip unnecessary instructions and context from your summarization prompts. A well-crafted 50-token prompt can produce the same quality output as a 500-token prompt — with 3-5x faster inference.
Not every article needs GPT-4-class processing. Configure your Skills to route content based on complexity:
Pre-compute formatted versions for each distribution channel. Do not re-render the same content for Telegram, Discord, and Slack at send time. Generate all formats during the processing stage and cache them.
OpenClaw supports native integration with major channels:
Not all stories have equal urgency. Implement a priority queue in your distribution Skill so breaking news jumps ahead of routine updates. This ensures your highest-value content has the lowest latency path to readers.
