Vladimir Ozerov commented on IGNITE-4295: ----------------------------------------- 1-5 -> done. > GridUnsafe: implement specialized methods for every kind of copy operation. > --------------------------------------------------------------------------- > > Key: IGNITE-4295 > URL: https://issues.apache.org/jira/browse/IGNITE-4295 > Project: Ignite > Issue Type: Task > Components: general > Affects Versions: 1.8 > Reporter: Vladimir Ozerov > Assignee: Vladimir Ozerov > Priority: Minor > Labels: performance > Fix For: 2.0 > > > 1) copy(OFFHEAP, HEAP) > 2) copy(HEAP, OFFHEAP) > 3) copy(OFFHEAP, OFFHEAP) > 4) copy(HEAP, HEAP) > 5) copy(T[], T[]) must be avoided and replaced with System.arrayCopy(). > 6) Add optional threshold. If we copy too small memory chunk which size is > below the threshold, then resort to byte-by-byte copying, as it will be > faster. > E.g. on PowerPC with OpenJDK 8, copying of <100 bytes of data is faster on > byte-by-byte basis. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
