Cache Memory
By default, the built in directory service cache will use half of the configured system memory.
This value can be adjusted by editing (or creating) the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\HealthCast\ExactAccess\Override
MAXInternalDBCacheSizeInMB: reg_dword = 8192
On a machine with 32GB of RAM, you can allocate 24GB of RAM to the internal SSO directory service cache, leaving the remaining 8GB for other services by specifying the value:
MAXInternalDBCacheSizeInMB: reg_dword = 24576
