semi-spaces and causes the heap size to increase by 3 MiB. The throughput
improvement depends on your workload (see [#42511][]).

The default value is 16 MiB for 64-bit systems and 8 MiB for 32-bit systems. To

The default value depends on the memory limit. For example, on 64-bit systems
with a memory limit of 512 MiB, the max size of a semi-space defaults to 1 MiB.
On 64-bit systems with a memory limit of 2 GiB, the max size of a semi-space
defaults to 16 MiB.

To get the best configuration for your application, you should try different
