> There is
> - durable memory segment in PDS enabled data region
> - page replacement started
> then Ignite performance slow down occurs, JFR & Visual VM shows get&put from
> FullPageIdTable requires significiant time to be executed
> {noformat}
> Avg steps in loaded pages table, get: 9456 steps, put: 20243 steps,
> capacity: 20242 size: 7978]
> {noformat}
> Effect of influence of FullPageID table is cumulative, once it starts to
> grow, number of steps required grows also.
