To facilitate parallel recovery, configure the maximum number of engines to be online at start-up.
Configure an optimal number of recovery tasks using the configuration parameter max concurrently recovered db. Recovery is I/O-intensive and the value should take into account the response time of the underlying I/O subsystem. This value can be set to 0 (which is the default) for Adaptive Server to determine the optimal number of recovery tasks.
As recovery uses only the default data cache, cache configuration should ensure that there is a large amount of default data cache for recovery.
If data space accounting is not essential for a database, set the database option to turn off free space accounting using sp_dboption. This disables threshold actions on the data segment.
