Почему Java имеет такое большое место?

Some initiatives:

• Since 1.5 class data sharing can be used;
• Java 6 update 14 brought in compressed oops which reduces the footprint of 64-bit JVMs with under 4GB of Heap.

По крайней мере, одна вещь является долгой историей Java - она ​​началась в 1995 году и теперь является версией 6. Сохранение обратной совместимости при добавлении функций неизбежно увеличивает ее объем. Это изображение в значительной степени говорит о ...

We have some server-side apps which do nothing but bridge multicast traffic (i.e. they have no permanent state). They all run with about 2.3 - 2.5 Mb of Heap on a 32-bit Java6 (linux) JRE.

Is this a big footprint? I could easily have a thousand of these on a typical server-class machine (from a memory perspective), although that would be bit pointless from a threading perspective!

That said, there is the Jigsaw project to modularize the VM (the libraries I believe) which is coming in Java7; this will help those who wish for smaller footprints.

I realize that this doesn't really answer your question but it is relevant nonetheless! What sort of applications are you designing where you are finding that memory footprint is an issue?
