Whatever efficiency may hypothetically be possible with Java, you can in-fact spot a real world Java program in the wild by looking for the thing taking up 10x the memory it seems like it should need… when idle.
Yes yes I’m sure there are exceptions somewhere but I’ve been reading Java fans using benchmarks to try to convince me that I can’t tell which programs on my computer are Java just by looking for the weirdly slow ones, when I in fact very much could, for 25ish years.
Java programs have a feel and it’s “stuttery resource hog”. Whatever may be possible with the platform, that’s the real-world experience.
