I take a lot of time to make a PC... but that's because I like to think my concept very thoroughly before I even pick up a pencil. Once I have that in mind, I can make a first level character in five to ten minutes.
Making high level characters takes a lot longer, obviously. I can make a 10th level character in half an hour to one hour. I made an epic Sorcerer 15/Incantrix 10/Archmage 5 once, and it took me several hours.
If we're talking NPCs, it's a lot faster. I'll just pick arbitrary stat scores, max every skill, and pick mostly standard spells; it takes me about half the time needed for a PC.
