Scalability and UI Performance

For optimal user interface performance, it’s important to allocate an appropriate amount of resources to your NAKIVO Backup & Replication instance. The following are the guidelines for allocating RAM to your instance based on the number of jobs created by this instance:

1. Up to 29 jobs: 2 GB of allocated RAM

2. 30–49 jobs: 4 GB of allocated RAM

3. 50–99 jobs: 8 GB of allocated RAM

4. 100–199 jobs: 16 GB of allocated RAM

5. 200+ jobs: 20 GB of allocated RAM
   

   Note
   The above guidelines refer to both active and disabled jobs.
   

If your instance has less than the recommended amount of allocated RAM for the respective number of jobs, consider adding more resources to the machine hosting the instance.

The machines used to open product web UI should meet the following requirements:

• Processor: 1.5 GHz or higher

• RAM: 1 GB or more
