General System Requirements for Confluence
As a general basis, Atlassian’s system requirements for Confluence apply, but the operation of a Linchpin Intranet Suite instance requires more resources. The different applications require different resources depending on their intended use.
These tables can serve as a basis for your own planning.

From these tables you can see that for a multi-node data center system with 2,000 users you should plan for approximately 16 GB RAM.
For a 2,000-user confluence system, this means approx. => 8-10 GB heap space. The Java code cache should be at least 512 or 768 MByte.
Please note, however, that these are only average orientation values!
In practice, an optimized heap results from the monitoring data and its analysis, in particular the heap usage, garbage collection and “time spent on garbage collection”.
Furthermore, the I/O speed and latency of the hard disk accesses should also be taken into account (especially with regard to the Confluence search index), as well as the “slow query logs” of the database system.
