[~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]

[~amashenkov], could you please confirm it would be useful for all users to set 
swap space lower than 10% (and we should include this suggestion to Ignite 
2.5(2.6) )?

AI docs recommends set this parameter to zero:
