Large difference of speed between solaris and rhel-5 when running est_noise

The same input data and parameters, it took solaris (dell precision 390 with 2GB RAM) 6 min to complete. While rhel-5 (dell optiplex 755 with 4GB ram) obtained results within fifty-six seconds.

Why so large difference in speed? Is the solaris not suitable for heavy load of numerical computations? Or the difference of RAM matters?
