hazelcast cache performance goes down

[Ciment Maltu]

Hi,

I upgrade payara full server to the 5.2021.3. I did some performance tests. I found, that cache performance was degradated x times  and this version (also 5.2021.2) is useless with hazelcast and JCache.

 I known that in these versions (5.2021.2 and 5.2021.3) some stuff arround hazelcast was changed.

Do you know about this issue? During performance I found in logs that get some stuff from the cache took 30-90seconds. In version (5.201) average time to get item from cache took 1-10ms.

Has anyone the same issue?

Thanks. ciment

I have tested this problem little bit more. 

I refactored serialization from default java serialization (implements Serializable) to more efficient way and it seems that problem with cache disappeared. Also I got better result from cache 0.5-2ms in average.

Custom serialization improves my speed 5-10 times

I will go do more tests accross whole application. 

Thanks ciment.
