Dimensionamento de servidor por visitantes.
Estime o tráfego de pico, visitantes simultâneos, pedidos por segundo, largura de banda e a CPU e RAM necessárias a partir dos visitantes mensais do seu site.
Traffic
2 = the busiest day has twice the traffic of an average day. Campaigns, launches and news spikes can reach 5–20×.
4.2 % means perfectly even traffic. 8–12 % is common for regional sites; global audiences are flatter.
Pages and caching
Everything a page downloads: HTML, scripts, styles, images, fonts.
WordPress page cache, Varnish, Nginx FastCGI cache or CDN HTML caching.
Application server
Measure with APM or a load test. Typical: 20–80 ms for light pages, 100–400 ms for heavy CMS or shop pages.
Time a worker stays busy, including database and API waits.
0 if the database runs elsewhere.

- This is a planning estimate built from your assumptions, not a measurement. Confirm with a load test (k6, Locust, JMeter, Gatling) on a staging copy before buying.
- Peak load, not monthly visitors, decides server size: visitors arrive unevenly, so the peak inputs matter most.
- Months are averaged to 30.44 days. Data sizes are decimal (1 MB = 1,000,000 bytes).

A planning estimate from your assumptions, not a measurement; confirm with a load test. Months are 30.44 days and data sizes decimal. Database servers and multi-region designs are not sized separately. Everything is calculated in your browser; nothing is sent or probed on the network.
Monthly visitors are converted to the busiest minute using the peak-day, peak-hour and burst factors. Little’s law gives concurrent visitors and workers; CPU is uncached pages × CPU time ÷ target utilisation; bandwidth is page views × page weight.
100,000 visitors a month, 3 pages each and 2.5 MB pages peak at about 0.8 pages per second and 16 Mbps: a 1 vCPU / 4 GB server with room to spare.
