SocketBufSize option

Specifies the chunk size at which to read the data from the source file, expressed in bytes.

Valid values are 64 KB - 2 GB, with a default value of 8 MB. Values outside this range result in a system notice that the value is reset to the appropriate minimum or maximum level. You can use this option to tune the performance of loads based on the speed at which the source data is available for loading.
