[~dmagda],
What about dots on the end at the existing suggestions?
WIll i add?
{code}
"Disable collision resolution (remove 'collisionSpi' from configuration)"
"Disable checkpoints (remove 'checkpointSpi' from configuration)"
"Disable local jobs marshalling (set 'marshalLocalJobs' to false)"
"Disable grid events (remove 'includeEventTypes' from configuration)"
"Use default binary marshaller (do not set 'marshaller' explicitly)"
{code}

> 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
