question about load big file (no replies)

I use "load data local infile ..." to load file which is 7 GB to mysql cluster. but just load 20,000,000 rows and spend 200 min. it spend too much time. Use MyISAM will load 90,000,000 rows and just spend 20 min.

Is it the problem of mysql cluster or my config file?
Please help me for the problem.

Best Regards!

4 data nodes
data node machine: 12 core cpu, 64GB mem

1 sql node : 12 core cpu 16GB mem
