What is the default value for initial-heap-size (minimum heap size) in Java 6?

Question

I know that it is 4MB in Java 1.4.2. And according to:

GC-Ergonomics

The Miniumum on server-class-machines is 1/64th of the machine's physical memory. But what is the initial heap in Java6 on Machines with 1 CPU and/or less than 2GB Memory (non server-class machines)?

Thx

Answer 1

According to Ergonomics in the 5.0 Java[tm] Virtual Machine , for non-server-class machines, the default values are the same as the default values for version 1.4.2 which are:

• initial heap size of 4 Mbyte
  
• maximum heap size of 64 Mbyte

Answer 2

Based on the link you have provided:

On server-class machines running either VM (client or server) with the parallel garbage collector (-XX:+UseParallelGC)

the initial heap size and maximum heap size have changed

that means other settings are not changed and their default values are same as 1.4.2 for all other cases.
