Default: 1

The AFS redirector as of 1.7.22 supports two I/O processing mechanisms. The new implementation is referred to as Direct I/O. Direct I/O provides two benefits over the prior implementation. First, it is faster. Second, it provides support for CreateFile(FILE_FLAG_NO_BUFFERING). When a file is opened with the FILE_FLAG_NO_BUFFERING flag set, the AFSCache is bypassed and all I/O operations on the file are performed directly to and from the file server.

0: use the older I/O processing mechanism.

1: use the new Direct I/O processing mechanism.
