> 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}}.
> {code}
> 10000  -> bytes
> 10 kb
> 64 mb
> 1 gb
> ...
> {code}
