Igor Besedin commented on IGNITE-15989:
---------------------------------------
[~zstan] There is one problem in the description. My cache config is using
onHeap caching. In version 2.8.1, repeated requests for cahe.get (key) for the
same key are executed several times faster. In versions 2.10.0, 2.11.0,
repeated requests for the same key are performed more slowly. After analyzing
the problem, I found out that in version 2.10.0, 2.11.0, enabling onHeap
caching does not affect performance, repeated requests for cahe.get (key) are
equally slow.

> After upgrading to version 2.10.0 (2.11.0) from version 2.8.1 I found
> performance degradation on repeated chache.get (key) requests on server nodes
> are executed in job's. In versions 2.10.0, 2.11.0, enabling onHeap caching
> does not decrease the execution time of chache.get (key) requests. In version
> 2.8.1 - when you enable onHeap caching, the execution time of repeated
> chache.get (key) requests will decrease several times.
