Minimum Hosting Requirements for WordPress by Visitors. How BotBlocker Reduces Resource Demands

Choosing the right server or cloud parameters for WordPress isn’t just about the CMS itself – it’s about your traffic, plugins, themes, and, most critically, your security setup. BotBlocker can dramatically change real requirements by blocking bots and attacks before they consume your resources. Below: practical recommendations for WordPress hosting at various audience levels and an analysis of how BotBlocker optimizes resource use.

Minimum Server Requirements for WordPress: The Official Baseline

  • PHP: 8.1 or higher
  • MySQL/MariaDB: MySQL 5.7+ or MariaDB 10.4+
  • HTTPS: Required
  • RAM: At least 512 MB for basic sites (not production)
  • CPU: 1 core, any modern CPU

Practical Minimums by Audience Size

Traffic (visits/day)RAMCPU CoresSSDRecommended Hosting Type

5,000–20,0002–4 GB2–4YesVPS, Cloud, Dedicated

Notes:

  • Always choose SSD/NVMe storage for performance.
  • CPU is less important than RAM for most WordPress sites.
  • WooCommerce, heavy plugins, or large media libraries may require more RAM and CPU.
  • Server location and quality of network/peering matter for global sites.

WordPress Bottlenecks: What Consumes Resources?

  • Processing each page load (especially with many plugins)
  • Handling “bad” traffic: bots, scrapers, brute force, spam
  • Database queries, especially on dynamic or e-commerce sites
  • PHP execution for every uncached visit

How BotBlocker Changes the Resource Equation

1. Blocking at the Earliest Stage (Early/MU Plugin Mode)

2. Standard Mode (Before Plugins and Themes)

  • Standard Mode: BotBlocker runs at the very beginning of the WordPress execution cycle – before any plugins or the theme.
  • Effect: Most harmful and unwanted traffic is filtered out before it can impact performance.

3. Real-World Impact on Hosting Requirements

  • Sites with BotBlocker: Require significantly less RAM and CPU compared to unprotected sites with the same visitor numbers.
  • On basic VPS hosting: You can serve double or even triple the number of real visitors versus an unprotected site (less load, fewer database queries, faster PHP).
  • Shared hosting: Less risk of account suspension due to resource abuse by bots.
  • E-commerce and membership sites: Fewer fake registrations, less brute force, lower risk of slowdowns during “attack” waves.

Sample Scenarios: With and Without BotBlocker

Without BotBlocker

  • A sudden spike of bot visits (scraping, brute force) can push a small VPS into swap or make the site slow/unresponsive.
  • Even with caching, every bot visit still initializes PHP and the database before being rejected.
  • Real users experience delays, host may limit/suspend account for “overuse”.

With BotBlocker (Early Mode)

  • Bot requests filtered at the very beginning – often without loading WordPress at all.
  • Database, theme, and plugin resources are not used at all by bad actors.
  • Server stays responsive for real visitors, even during attacks.
  • Can safely run a medium-traffic site on minimal hardware, with better user experience.

Recommendations: Minimum and Optimal Parameters

For up to 1,000 real visitors/day:

  • 1 CPU core, 1 GB RAM, SSD, basic VPS/shared (with BotBlocker)

For 1,000–5,000 visitors/day:

  • 2 GB RAM, 1–2 cores, SSD, managed VPS/cloud

For 5,000–20,000 visitors/day:

  • 4 GB RAM, 2+ cores, SSD/NVMe, consider cloud scaling

For heavy WooCommerce, membership, or multilingual:

  • Add at least 1–2 GB RAM above “normal” minimums

With BotBlocker (any mode):

  • Reduce recommended specs by up to 30–50% versus a site with no protection, especially during spikes.

Always:

  • Enable PHP Opcache
  • Use the latest PHP version
  • Keep MySQL/MariaDB tuned and updated
  • Enable HTTP/2 for SSL sites

FAQ

Does BotBlocker work on any hosting?
Yes

Can BotBlocker replace a CDN or caching plugin?
No, but it reduces backend load so cache/CDN works more efficiently.

Is early blocking safe for all sites?
Yes. Always test after enabling “early” or MU mode.

Can BotBlocker save money on cloud/server bills?
Yes – by blocking non-human load, you can choose a cheaper hosting plan or handle higher loads with the same resources.
