> I'd like to suggest performance improvement for java.io.DataInputStream, java.io.DataOutputStream, java.io.ObjectInputStream, java.io.ObjectOutputStream and java.io.ObjectStreamClass classes. This improvment includes two patches. First patch (for java.io.DataInputStream & java.io.DataOutputStream) gives boost on SPECjvm2007 serial benchmark - 9.5%. Second patch (for java.io.ObjectIputStream, java.io.ObjectOutputStream & java.io.ObjectStreamClass) gives boost on SPECjvm2007 serial benchmark - 2%. Together both patches give boost on SPECjvm2007 serial benchmark - 26.5%.
