CI build runners: server sizing for Nigerian teams

Measure the busiest useful workflow

For ci build runners, the starting measurements are build duration and peak concurrent job memory. Use a realistic dataset and record quiet-period and busy-period results separately. A fresh installation with no history, uploads or simultaneous users does not represent the environment you will eventually operate.

Benchmark the largest build with cold and warm caches. Limit parallel jobs according to RAM, CPU and temporary disk consumption.

Build a capacity worksheet

Record the observed CPU peak, working memory, persistent storage, temporary storage and data transfer for the same test window. Include the operating system, monitoring and backup activity. Distinguish sustained pressure from a short spike before deciding which resource is limiting progress.

Use this acceptance check when comparing two configurations: A clean build produces the expected artefact and a failed job cannot modify the production server. If the faster configuration fails this workflow, its headline benchmark is not enough to justify a purchase.

Test from Nigerian user networks

Run the ci build runners workflow from the office connection and at least one mobile connection your users rely on. Record the test location and network alongside server measurements. A Nigeria-focused product page does not establish where the server is physically hosted; confirm the offered region and measure the route before choosing it.

Turn results into a purchasing decision

Compare the measured requirement with the exact available plan, including usable disk, transfer allowance and upgrade options. Ask what happens when a limit is reached. Confirm software compatibility and licensing separately; hardware capacity alone does not establish whether the complete application is supported.

Budget in naira using the current checkout price. Add backup storage, paid software, maintenance and a contingency appropriate to your business. Save the assumptions and repeat the test when workload or user behaviour changes.

Server sizing worksheet

Use these prompts in your project notes. Replace general targets with measurements and an accountable owner.

How much RAM does ci build runners need?

There is no reliable figure based only on the application name or number of registered users. Measure the active working set during your representative workflow, include supporting services and leave documented operating headroom. Compare that evidence with a plan you can expand when needed.
