64位操作系统上的32位或64位应用程序？ [英] 32-bit or 64-bit application on 64-bit OS?

问题描述

我们正在开发一个由Java编写的swing应用程序，它只需要大约128MB的内存，在短期内我不会看到它需要更多的内存，如4GB。以前我们总是提供3个不同的版本，一个用于32位Windows，一个用于32位Linux，另一个用于64位Linux，安装程序包含JRE。
直到几周之前，任何人都没有使用64位版本，并且报告了OutOfMemoryException，因为该应用程序比32位版本消耗的内存大约多40-50％。

We are developing a swing application written by Java which requires only about 128MB memory, and in the short future I don't see it will require much more memory like 4GB. Previously we provide always 3 different releases, one for 32-bit Windows, one for 32-bit Linux and another for 64-bit Linux, with an installer which has JRE included. The 64-bit version was not used by anyone until couple of weeks ago, and an OutOfMemoryException was reported because the application consumes about 40-50% more memory than the 32-bit version.

我的问题是，如果应用程序永远不需要使用超过4GB的内存，我们是否需要为64位Linux提供64位版本？我们进行了一些快速测试，结果显示32位版本也适用于64位Linux。但我不确定我们可能会有什么缺点，例如：性能和/或兼容性问题？

My question is, is it needed at all for us to provide the 64-bit version for 64-bit Linux if the application will never need to use more than 4GB memory? We had some quick test which revealed that 32-bit version works also on 64-bit Linux. But I'm not sure what could be the cons we would have, e.g. performance and/or compatibility issue?
