Super slow load data infile with index

I am loading tab delimited data from numerous files into a newly created table. If I use three non-unique value indexes then load times increase almost exponentially. Without index, loads times are almost linear with number of records.

File Records Time w/index Time w/o index
1 981,775 94.6 60.6s
2 938,626 116.6 55.6
3 993,750 158.1 56.5

What can I do to speed up the loading with indexing?
