NOBODY YELL AT THIS GUY! OK, I also fell vixtim of asking what r_speeds are at one point in time. You better hope Kol never comes back because he will hunt you down man. For future reference, look for the question your asking in the forums before you ask it. But here is what r_speeds are:
R_speeds are how much of the level Half Life can handle at a time. IF you have a small encolsed area or a big area surrounded by walls so tha you cannot see the whole thing, the r_speeds will be low, thus producing a very smooth, non-lagging map. IF you have a huge block of a map where ou can see the whole thig then the r_speeds can rack up and the map will lag. If you dont know what I mean then build a huge hollow block map with no walls and play it. It will lag.
