Hardware requirements

Tempus Serva is a highly optimized platform, that will run on even the smallest server configurations: The software will even run on the Rasperry PI (worlds smallest common Linux platform). For running EC2 instances small server is recommended, allthough micro instances will do ok for minor installations (few concurrent users / few parallel installations).

Normal requirements for the memory are

  • Recommended minimum 1024 mB RAM for the heap (application)
  • Recommended 256 mB RAM for PermGen (older java versions)

Running lower is possible, but can result in reduced performance and classloader errors (dependening on which features are used).

  • Minimum 128 mB RAM for the heap (application)
  • Minimum 64 mB RAM for PermGen (older java versions)

Memory intensive operations include OLAP analysis, document building and large data sets (+20k records).

Check Platform metrics for further information.
