> Currently we have GridPerformanceSuggestions that output suggestions to logs
> on Ignite start on how Ignite can be improved.
> I suggest to go a little bit deeper and validate more configuration options
> and add validation for JVM and OS settings.
> Ignite should output warning if:
> * GC logging is not enabled
> * MaxDirectMemorySize is not set (-XX:MaxDirectMemorySize)
> * Heap size is greater than 30,5G and JVM cannot use compressed oops
> * Any of the recommended OS setting described here
> https://apacheignite.readme.io/docs/jvm-and-system-tuning are not properly
> set
