This setting can be used to optimize system performance under high traffic scenarios. This setting determines a size or block of values that OnBase will cache when retrieving Lockbox transactions. This setting is adhered to until the OnBase session is closed or the maximum block size is reached. If the maximum block size is reached, another block is allocated. This approach can be used to prevent potential deadlocks in high-volume Lockbox environments. A value of 100 is recommended. For systems where high-volume traffic is not a concern, this setting should not be defined.
