> Configure Memory Sizes with units

> Currently, memory sizes are configured by pure numbers, the interpretation is
> different from configuration parameter to parameter.
> For example, heap sizes are configured in megabytes, network buffer memory is
> configured in bytes, alignment thresholds are configured in bytes.
> I propose to configure all memory parameters the same way, with units similar
> to time. The JVM itself configured heap size similarly: {{Xmx5g}} or
> {{Xmx2000m}}.

> 10000 -> bytes
> 10 kb
> 64 mb
> 1 gb
