[~rsandberg], why do you think so?
{quote} you still might like to set this param <= 10, which is still within the
recommendations.
{quote}
Where do you read such recommendation?
Here are documents, which recommend setting the value to 10 strictly (not less):
[https://apacheignite.readme.io/docs/durable-memory-tuning#section-adjust-swappiness-settings]
[https://apacheignite.readme.io/docs/jvm-and-system-tuning#section-memory-issues]
Same in official RHEL recommendation for databases:
[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/performance_tuning_guide/s-memory-tunables]
