The recommended memory allocation for signer depends on the amount of RAM available on the host. In addition, also the type of host (virtual, physical etc.) and usage patterns of the Security Server effect on the most optimal amount of memory. The table below shows general recommendations regarding the amount of memory allocated for the signer component.
RAM on host (GB) | SIGNER_PARAMS value |
|---|---|
4 | -Xms50m -Xmx100m |
8 | -Xms50m -Xmx150m |
16 | -Xms50m -Xmx200m |
31 | -Xms50m -Xmx200m |
| Info |
|---|
The default memory allocation for signer is -Xmx50m. In production environments the allocation should be increased. |
