LOAD DATA INFILE poor performance

mariadb documentation https://mariadb.com/docs/reference/col6/cli/cpimport/ ,says

"If the LOAD DATA [ LOCAL ] INFILE or INSERT INTO .. SELECT FROM .. statements are used with a ColumnStore table, MariaDB Enterprise ColumnStore 6 transforms the operation into a bulk load that uses cpimport by default"

The performance between LOAD DATA INFILE and cpimport by loading from the same file, there's a huge difference. Below is the log.
