Chapter 2. Hardware recommendations

RAM is the most important hardware feature to size properly. Make sure your system has enough RAM available. Typical RAM requirements are:

  • For 10,000 users and 100 groups: at least 4 GB of RAM and 4 GB swap space
  • For 100,000 users and 50,000 groups: at least 16 GB of RAM and 4 GB of swap space

For larger deployments, it is more effective to increase the RAM than to increase disk space because much of the data is stored in cache. In general, adding more RAM leads to better performance for larger deployments due to caching.

Note

A basic user entry or a simple host entry with a certificate is approximately 5—​10 kB in size.
