Dmitriy Pavlov updated IGNITE-7638:
-----------------------------------
Description:
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 (~5-10% оf samples)
{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.
