Space memory management in XAP.NET

I wondering how to set up memory management for the space using XAP.NET (there are a lot of articles about Java). I found the setting in docs, but its working only for Java, not .Net version of gigaspaces: space-config.engine.memory_usage.high_watermark_percentage

So, how can I configure high_watermark_percentage for GSC for .NET version of gigaspaces?

thank you for answer! To clarify some details I'd like to show an examples. To set up memory with your Processing Unit config file - pu.config - you can just add a few line:

      <add Name="mjGame">
          <add Name="space-config.engine.cache_policy" Value="0"/>
          <add Name="space-config.engine.cache_size" Value="100000"/>
          <add Name="space-config.engine.memory_usage.high_watermark_percentage" Value="60" />
          <add Name="space-config.filters.Statistics.enabled" Value="false" />
          <add Name="space-config.engine.memory_usage.write_only_block_percentage" Value="58"/>
          <add Name="space-config.engine.memory_usage.write_only_check_percentage" Value="55"/>
          <add Name="space-config.engine.memory_usage.low_watermark_percentage" Value="40" />

if you wanna set up global setting for all the GSC instances - you should use a default setting file located here: C:\GigaSpaces\XAP.NET-10.2.1-x64\NET v4.0\Config\Default.config and use SystemProperties section for the settings:

        <add Name="com.gs.engine.cache_policy" Value="0"/>
        <add Name="com.gs.memory_usage_enabled" Value="true"/>
        <add Name="com.gs.filters.statistics.enabled" Value="false"/>
