Hello,
We'd like to propose to back-port our FileChannel.transferTo() performance improvement for Windows that was recently accepted into OpenJDK v9 and v8 to v7. The original JDKv9 fix just for reference: http://hg.openjdk.java.net/jdk9/dev/jdk/rev/ba6d8f56003b. Our suggested webrev patch for OpenJDK v7 is attached to this email, based on our understanding of the back-porting steps. Your review and acceptance of this contribution would be appreciated. Best regards, Martin Sawicki (and Kirk Shoop, and Valeriy Kopylov) Microsoft Open Technologies, Inc. A subsidiary of Microsoft Corp.
