If MonetDB could use table partition ?

I am using "COPY BINARY INTO ...FROM ..." to insert 1000 FITS files into a table and the table has 21 columns, every FITS file has 200000 records. After some FITS files, the loading becoming very slowly, so If MonetDB could use table partition to accelerating the copy? or if Data Vaults could be loading more quickly? Thanks! Meng
