我在Linux上有一台8 GB RAM和32位JVM的机器，我想让JVM使用最大的RAM

Question

I have a machine with 8 GB RAM with 32 bit JVM on linux and i want to make JVM to use maximum USE OF RAM , I think if i increase Heap size memory then Garbage Collector will become slow. Is there other solution to improve processing speed ?. thanks in advance.

Answer 1

Install a 64-bit version of Linux and Java.

If you have a 64-bit processor, you can run a 64bit VirtualBox on a 32bit OS. Source

Answer 2

If it is an Oracle JVM you cannot use all that memory.

Upgrade to a 64 bit JVM suitable for the platform.

Answer 3

may be run 2 32 bit Java virtual machines. There is no other way to utilize 8GB, if you cant upgrade to 64 bit.
