64-bit operating systems

A 64-bit operating system will allow you to increase various settings in Splunk to improve performance.


indexes.conf

maxQueryIds = <non-negative number> (10000000)The maximum number of ids a search will attempt to resolve in a single query. This is a good value for 32-bit systems. It can be raised for 64-bit installations with large amounts of RAM.
maxDataSize = <non-negative number> (750)The number of MB's db hot is allowed to grow to before it is rolled out to warm. This number should not be increased unless Splunk is running in 64-bit mode.
