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]

Effect of influence of FullPageID table is cumulative, once it starts to grow, number of steps required grows also.
