Recommended requirements



Our recommendations are based on the following presumptions:

  • Only 10% of all websites on shared hosting are active (have any persistent number of visitors per week/month).
  • 128 MB of RAM is fine for most typical websites.
    • WordPress: 64 MB
    • Joomla: 64 MB
    • Drupal: 128 MB
    • Symfony: 128 MB
  • No more than 1-3 simultaneous visitors per website, no more that 500 unique visitors per website per day.


If the above is true, we recommend having 1GB of RAM for every 40-50 websites on a shared hosting node.

If you are hosting websites that generate more traffic (5-10 simultaneous visitors per website, between 1000 and 30000 unique visitors per website), we recommend having between 500 MB and 1 GB of RAM per website.

In addition, having sufficient disk space for memory swapping is highly recommended:


Amount of RAM on the server Recommended free disk space for swapping
Less than 1 GB 1 GB
1 GB or more 1/2 * the amount of RAM



Disk space


We recommend having this much disk space for hosting:


Type of hosting Recommended free disk space for websites
Typical shared hosting (100-500 websites per server) Between 2 and 2.5 GB per website
Dedicated VPS hosting (1-10 websites per server) Between 4 and 12 GB per website
