[infinispan-issues] [JBoss JIRA] (ISPN-3690) Lower allocation cost of instances of org.infinispan.commands.read.GetKeyValueCommand

Dan Berindei commented on ISPN-3690:
------------------------------------
This was actually implemented with ISPN-5032.
TBH I'm not very fond of the extra {{InternalEntryFactory}} reference in
{{GetCacheEntryCommand}}. It's used to synchronize on the cache entry, but why does
{{GetCacheEntryCommand}} need to copy the entry fields atomically while the rest of our
code non-atomically reads the value and the metadata separately?
Lower allocation cost of instances of
org.infinispan.commands.read.GetKeyValueCommand

Key: ISPN-3690
URL: https://issues.jboss.org/browse/ISPN-3690
Project: Infinispan
Issue Type: Enhancement
Components: Core
Reporter: Sanne Grinovero
Priority: Minor
Labels: performance
Classes of type {code}org.infinispan.commands.read.GetKeyValueCommand{code} have an high
cost in terms of memory allocation.
Would be great if we could reduce the runtime cost: in an app server test of just 25
minutes - which is stressing way more systems than just Infinispan - just the occasional
get operations 43GB of memory accumulated over time.
This is a high cost on the TLABs, skewing various other values, among others making the
default GC options unsuitable.
