HLVIS is SLOWFrom here

For most well designed maps, vis should have a worst case run time of about 45 minutes on a single p2-300 class computer. If it is taking longer, then the map probably needs work to add vis blockers. Several things can make vis take way longer than usual:
First, if the world has been 'boxed in' to prevent leaks, vis has to spend large amounts of time on the exterior gaps which would normally not exist on a map without a box.
Second, The architecture which connects 'areas' together might be a bit confusing for vis to figure out. It is somewhat difficult to explain, but a few examples would be: halls lacking a wall somewhere which is not directly on the XZ or YZ plane; halls that intersect rooms on a plane other than XZ or YZ, large rooms with walls that are not vertical; halls that connect two areas but the areas can see each other through the hall; Lots of little tiny brushwork in an area (especially large areas) that is not an entity.
Third, vis is quickly brought to a crawl by large outdoor areas that are not extremely carefully constructed to not too see much 'indoors'..
And finally, using an older version of gensurf that does not support ZHLT's HINT brushes.
It is highly advised experiment heavily with test maps with sample architecture, using software mode, r_drawflat 1, and r_draworder 1 in order to see how vis works. Also, read the HINT brush tutorials described in the section on HINTs.
