Over 30mins to generate the first eigenvector?

Is it normal for Mathematica to take over 30mins to try to compute the first eigenvector of a 100x100 matrix (http://pastebin.com/qfPQv9LQ)? The matrix is reasonably sparse - about 90% of the cells are 0s.

The command I'm using is

N[Eigenvectors[m, Quartics -> True][[1]]]

where m is assigned to the matrix.

My machine is an i5 3ghz and the process still isn't terminated yet. It's a quad core machine, but only one of the cores is being maxed out for over 30mins.
