IronPort recommends setting this value to 10% of the
“Maximum main table segment size” value.

Build all indices simultaneously
Indicates that Sawmill for IronPort should build all indices
at the same time instead of sequentially.
Enabling this option can increase database creation
performance, but also requires more RAM.

Build cross-reference tables in threads
Indicates where Sawmill for IronPort builds the cross
reference tables when it is configured to use multiple log
processing threads (one for each processor).
When Sawmill for IronPort is configured to use multiple
log processing threads:
• Option is enabled. Each process builds cross reference
reference tables when it is configured to use multiple log
processing threads (one for each processor).
When Sawmill for IronPort is configured to use multiple
log processing threads:
• Option is enabled. Each process builds cross reference
tables for the table segments in that process.
• Option is disabled. The main process builds the cross
reference tables for the main database table after the
table segments for each process have been merged into
the main table.
table segments for each process have been merged into
the main table.
