I have a csv file with 300000000 million lines.

when I load it in a MonetDB table, it takes more than 16 hours, whereas in Oracle it only takes 15 minutes. Where is the problem?

I use mclient as follows :

mclient -u user1 -d demo -ims -s " COPY 300000009 RECORDS INTO LINEORDER FROM STDIN USING DELIMITERS '|','\n'" - < D:\SSB\LINEORDER.tbl

cordially.
