Is your OpenClaw becoming slower with time? That’s because every cron job gets loaded into context Fix it with this prompt: “ Check how many session files are in ~/.openclaw/agents/main/sessions/ and how big sessions.json is. If there are thousands of old cron session files bloating it, delete all the old .jsonl files except the main session, then rebuild sessions.json to only reference sessions that still exist on disk." This will delete all the session data around your cron outputs. If you do a ton of cron jobs, this is a tremendous amount of bloat that does not need to be loaded into context and is MAJORLY slowing down your Openclaw If you for some reason want to keep some of this cron session data in memory, then don't have your openclaw delete ALL of them. But for me, I have all the outputs automatically save to a Convex database anyway, so there was no reason to keep it all in context.” Credits: @AlexFinn

@RoundtableSpace Less context, more speed instantly

@RoundtableSpace cron context bloat is one of those painfully real hidden taxes

@RoundtableSpace cleared 10k sessions, speed restored

@RoundtableSpace @RoundtableSpace wow, I didn’t realize that was the reason. had no idea old session files could slow it down like that. gonna check mine now!

@RoundtableSpace Yeah, OpenClaw cron bloat is a silent killer thousands of tiny .jsonl files explode sessions.json and murder context loading speed. That cleanup prompt is gold: nuke old cron sessions, rebuild sessions.json lean. If you're already dumping outputs to Convex smart move,

@RoundtableSpace Context accumulation is a feature that becomes a bug at scale. The real moat isn't just what an agent can do — it's whether it does it efficiently after months of operation. Built-in lifecycle management = sustainable agents. Manual fixes = technical debt.

@RoundtableSpace context bloat is the silent killer of long running agents. the model doesn't get dumber. it gets slower and more expensive because it's dragging thousands of old cron sessions into every new call. cleaning sessions isn't maintenance. it's performance engineering

@RoundtableSpace This is a good example of how “memory” becomes a liability at scale. Agent frameworks default to accumulating context, but without lifecycle management, you end up paying a performance tax. Feels like we’ll need built-in memory pruning strategies, not manual fixes like this.

@RoundtableSpace Interesting that the real fix is architectural, not operational. Offloading outputs to something like Convex and keeping the agent’s working memory minimal is closer to how real systems scale. Agents shouldn’t remember everything just what’s actionable right now.

@RoundtableSpace So basically… OpenClaw is remembering too much 😂

@RoundtableSpace Haha, OpenClaw thinks it's too cool for manual maintenance? 🤖 Let's declutter its brain! Try checking those .

@RoundtableSpace Reminds me of the days of low disk space and manual cleanup

@RoundtableSpace this is super helpful

@RoundtableSpace Performance issues can occur if excessive session data accumulates over time, so pruning or archiving old sessions is typically the practical way to maintain responsiveness.

@RoundtableSpace this bloat is real for cron heavy users

@RoundtableSpace This is a classic context bloat issue, too many session files being loaded over time kills performance. Cleaning old cron sessions keeps OpenClaw fast and efficient.

@RoundtableSpace nice i needed this

@RoundtableSpace you might wanna consider being openclaw ambassador
