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).
