If you mean "when properly installed", pretty well.
If you mean "as actually used", not at all.

With the exception of the very small raised floor under
the HP-3000 in my high school, every place I've encountered
raised floors there were "permanently removed" tiles, tiles
with corners cut off, tiles with large holes drilled into their
centers, etc. etc.
