1. The pwf file (with saved data about waypoint positions and connections) is usually less than 200 KB, so I don't think it can generate any problem for the server, the space on HDD etc.
2. From that what I remember the difference between yapb/epodbot and podbot mm waypoint format is the interpretation of camp waypoint data. So if You are using wrong file type (not right for Your bot) bots will look at strange directions at cam waypoints. I don't know if this is the only difference (You may need to ask at yapb and epodbot forums).
3. Amount of waypoints and amount of connections are affecting the CPU usage. The length of the path doesn't change anything. If You have more empty spaces - the density of waypoints should be lower - no need to put so many waypoints in open areas. But make sure if You need all connections between waypoints - usually there is a lot of unnecessary connections while waypointing the map. There is a code which is trying to prevent this automatically, but You still need to look and watch if this what the waypoint editor connects for You, You really need,
