The LOGBUFF configuration parameter and memory utilization

The LOGBUFF configuration parameter determines the amount of shared memory that is reserved for each of the three buffers that hold the logical-log records until they are flushed to the logical-log file on disk. The size of a buffer determines how often it fills and therefore how often it must be flushed to the logical-log file on disk.

If you log smart large objects, increase the size of the logical-log buffers to prevent frequent flushing to the logical-log file on disk.
