# Resource Requirements

## Load

For fastest response, run `rvcache` on a computer with a light processing load.

## Storage

The exact amount of required storage space varies with three factors—the storage mode, the number of subjects cached, and the size of the stored message values.

| • | In standard operation, `rvcache` keeps a table of cached subjects in memory, while it keeps message data for those subjects in a store file on disk. The computer running `rvcache` must have sufficient storage of each type.

| • | In memory-only mode, `rvcache` keeps both in memory (both the table of cached subjects and the message data). The computer running `rvcache` must have sufficient memory. (For background information, see Memory-Only Mode.)

## Distributed Caches

In some cases, you may find it expedient to distribute the resource requirements and the processing load among several computers. To achieve this goal, you can run several process instances of `rvcache` on separate computers. However, it is important that various process instances of `rvcache` cache disjoint sets of subjects (see Avoid Duplicates).
