What is k6 by Grafana Labs?

k6 is an open-source load-testing tool from Grafana Labs. It simulates many visitors using a site at once and measures response times, throughput and errors.

What does P95 latency mean?

95% of requests were answered faster than this time. It shows what nearly every visitor experiences, not just the average.

Why does Redis improve WordPress performance?

Redis keeps the results of frequent database queries in memory, so WordPress doesn't rebuild them on every page load. Dynamic pages and logins benefit most.

Are these tests run on production infrastructure?

Yes. We test on the same server setup and plan resources our customers use.

Will my site always match these results?

Not exactly. Your theme, plugins, content and traffic patterns all affect speed. The results show how each plan's resources perform under the same load.

Real-world performance, proven by testing.

We load-test our plans with k6 at 1,000 simultaneous visitors for 10 minutes. These are the latest results, broken down by plan and scenario.

What each plan runs on

CPU, memory and caching decide how your site holds up under real traffic. These are the resources behind each tested plan.

Personal

For low-traffic sites, blogs and personal projects.

CPU: 2 cores
Memory: 1 GB RAM
Redis object caching: Disable

Business

2× RESOURCES

For growing sites, higher traffic and demanding workloads.

CPU: 4 cores
Memory: 2 GB RAM
Redis object caching: Enable
