RE: Export of very big table

Also try with big buffer(as allowed by your physical memory) and commit=y which will help in faster import.

Have you dropped your indexes (if possible) prior to the import? The import will occur many times faster if no index maintenance is needed. Also, you may
want to have analyze=n in the parfile (analyzing a large table may add hours to
the import time).
