By default SV Server uses database to get the required data during simulation. It has however an ability to pre-load the data and run the simulation just from the memory (although the database is still needed for everything else). This can typically result in TPS increase between 10% - 30%. In case DB is having performance issues during simulation, these numbers could be even higher.

Warning #1: This configuration has impact to whole SV Server, so all virtual services running on it would be running from in-memory.

Warning #2: if you want to benefit from in-memory simulation the most, don't use custom conditions as those cannot be evaluated in-memory, but are always executed on DB level.

To enable inMemory simulation:

1. Locate the configuration file for SV Server, which is by default stored in following location:
   1. Windows:

      c:\Program Files\Micro Focus\Service Virtualization Server\Server\bin\HP.SV.StandaloneServer.exe.config

   2. Linux:

      /opt/microfocus/sv-server/bin/HP.SV.StandaloneServer.exe.config

2. Make a backup of the configuration file
3. Open it in a text editor
4. Search for "ServiceCallDataProviderProxy" and change it like below:

   <add key="ServiceCallDataProviderProxy.SelectedObjectName" value="inMemory" />

5. Save the configuration file and restart your SV Server
