good point -- fromfile() can be much faster for the simple cases it can

That depends on what the data mean. Is it a 2-d array with missing
values? If so, how do you know which are missing? Are there the same
number of tabs in each row? If do than loadtxt should be able to handle it.
You may be best off looping through the file:
for line in file:
a = numpy.fromstring(line, sep='\t', dtype=np.float)
and do what makes sense with each line.
