If the write is performed using heap buffers, the OpenJDK/Oracle implementation will create a cache of direct ones, performing a copy into it before writing into the file. Using a cached (per Page) instance of direct buffer will reduce the pressure on the GC (lowering the memory footprint at runtime) and will improve the NIO's write efficiency. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
