Why Your Redis Benchmark Ignores Network Jitter (and Why It Shouldn't)
You've just finished a week of tuning your Redis cluster. The benchmark numbers look fantastic: 99th percentile latency under 1 ms, throughput over 10...

What to Fix First When Redis Fork Latency Spikes Under Write Load
You're watching your Redis latency graphs, and suddenly — a spike. Not a gentle rise, but a cliff. P99 jumps from 2ms to 500ms, sometimes over a secon...
Choosing Between LRU and LFU Eviction Without Guessing Capacity Needs
Memory's finite. Always has been. When Redis hits its maxmemory limit, something's gotta give — keys get evicted. But which keys? That's where evictio...
When Redis Cluster Rehashing Stalls Your Pipeline: A Qualitative Benchmark
You're running a Redis Cluster at scale. Your pipeline is humming—thousands of commands per second. Then a rehashing event kicks in: slots migrate fro...
Pipeline Throughput Benchmarks
When Throughput Benchmarks Show Green but Production Still Crashes
You have run the yield benchmarks. Green across the board. 10,000 requests per second sustained. Graphs look like a surgeon's heartbeat. Then the pipe...

Why Your Next Benchmark Should Start With a Pipeline Backpressure Test
Benchmarking a pipeline without a backpressure trial is like testing a car's top speed with the parking brake on. You might get a number, but it tells...
Latency Tail Optimization
Fixing the Tail Without Sacrificing Throughput: A Qualitative Benchmark Approach
There is a quiet war in every latency-sensitive setup. On one side: yield—the raw volume of labor completed per second. On the other: tail latency—the...
When Redis Stops Being a Cache: A Guide to Using It for Real
Redis has been called the Swiss Army knife of databases. And it kind of is. But a Swiss Army knife can also cut your hand if you use it wrong. I have ...

What to Fix First When Pipeline Throughput Plateaus Below Target
You've added more workers. You've scaled the cluster. Yet yield sits at 85% of your target — and it won't budge. That plateau isn't a hardware limit; ...

When Pipeline Benchmarks Lie: Why Your Throughput Numbers Don't Match Production
Here is a story you have lived. Monday morning. You deploy the new pipeline – the one that benchmarked at 8,000 events per second in staging. By Tuesd...

Batch Size vs. Latency: Which One to Tweak First in Throughput Benchmarks?
If you have ever watched a yield graph plateau while latency climbs, you already know the tension: lot size and latency are not independent knobs. But...

When Your Pipeline Throughput Drops Below the Wire: What Changed?
You are watching the SCADA screen at 2 AM. The flow rate line—normally a steady plateau—has been sagging for three hours. Not a crash. Not a spike. Ju...
