In Adaptive Server Enterprise 12.5.0.3, the checkpoint task in a specified database executes up to 200% faster, according to internal benchmarks.This increase in checkpoint speed can cause significant gains in database recovery speeds. The checkpoint feature enhancement is automatic, and requires no action on the user’s part.
Issuing a larger batch I/O of dirty buffers causes this increase in checkpoint speed. The new default value of the I/O batch size is 100.
