in the first 20 levels... you should level fast...
(killing a level 2 monster at level 1 will level u up
)
Then it starts to go slower... not by much...
30-40
If you dungeon party (dp) leveling might take an hour... but it really doesnt seem that long
40+
Each level will seem to take a while but if you do quests like Rohas Request (they give lots of exp, but low jp), you will level purty fast
You can also start dungeon soloing... but it may be faster to level on like sirens
