/**
* The suite test will incrementally increase the load and execute searches.
* Each test run thus adds nodes and executes different benchmarks. This way we measure time taken for
* benchmark execution.
*
*
* The following system JVM properties can be defined to configure the suite.
*
* -
*
loaders - Controls the number of concurrent threads for loading blobs initially.
* Defaults to 1.
*
* -
*
testers - Controls the number of concurrent tester threads. Defaults to 1.
*
* -
*
nodeLevels - Comma separated string property that governs the depth and the number of
* nodes in the hierarchy. Defaults to 10, 5, 2.
*
* -
*
densityLevel - Controls the percentage of root nodes which will have sub nodes created.
* Defaults to 100.
*
* -
*
index - Controls if the index definitions are to be created. Defaults to false.
*
* -
*
asyncIndex - Controls whether the indexing is async. Defaults to false.
*
* -
*
noFullIndex - Controls whether fulltext indexing is enabled or disabled. Defaults to false.
*
* -
*
randDate - Controls whether to generate random dates in a range. Defaults to false.
*
* -
*
customType - Controls if nodes created in the load have a custom node type. Defaults to false.
