It is possible to tweak the batch size when doing an LDAP sync.
The insert batch size limits the amount of data being inserted in one transaction (for example, 100 users per transactions are inserted). By default, this is 5. The query batch size is used when data is fetched from the SkyVault Process Services database (for example, fetching users to check for deletions when doing a full sync).
