Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

Sorting I/O

Table 5–5 lists the startup parameters you use to improve performance when sorting records for reports and during index rebuild operations.

Table 5–5: Startup parameters for tuning sort performance 

Startup parameter	Description
Speed Sort (-TB)	Increase this parameter to 8K, 16K, or even 31K, particularly for index rebuild operations. Increasing this parameter increases memory usage during sorting and index rebuilds. It also slightly increases disk space usage.
Merge Number (-TM)	Increase this parameter to 32 to speed the merge phase of the sort process (at the cost of increased temporary memory usage).

For more information about these startup parameters, see OpenEdge Deployment: Startup Command and Parameter Reference .
