Summary: Investigate CHM8 allocations in GridDhtTxLocalAdapter. Key: IGNITE-2583 URL: https://issues.apache.org/jira/browse/IGNITE-2583 Project: Ignite Issue Type: Sub-task Components: cache Affects Versions: 1.5.0.final Reporter: Vladimir Ozerov Fix For: 1.6 *Problem* Whenever GridDhtTxLocalAdapter is allocated, two CHM8-s are created immediately: "nearMap" and "dhtMap". This is visible as a memory hotspot, which is responsible for >2% of overall allocations during single PUT. *Proposed solution* 1) Investigate whether we really need concurrent semantics here. Can these maps be replaced with HashMap-s or (HashMap + synchronzied)? 2) Investigate whether we can optimize for single-mapping scenario. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
