There's more of a nuance to it, though: “large” emphasizes volume. You talk about things being large when you're talking about the space they occupy or the empty space you can use within them. Saying that a knife is large would be strange, wouldn't you agree? It can be big, but not large, because it normally only extends in a particular direction. Same thing with a building that is really high, but not wide. A dish or a cup, on the other hand, you can comfortably describe as large.

“Profit” being “large” sounds really odd to me. Then again, a big profit sounds like something a child would say; this sentence would sound best if it had “a lot of profit” in it and it was somewhere in the predicate, but that wouldn't work as a translation of the Indonesian sentence, now would it? :/

I agree with joeldipos. But apparently "high profit" has become more common than "large profit".
