[cvsnt] wnt_fclose and FlushFileBuffers

[John Goehringer]

Tony,

    I'm seeing poor performance on both the client and server
with build 69 compared to build 68 and tracked it down to
the FlushFileBuffers call in win32.c:wnt_fclose.

    Was this for AtomicCommits support? Perhaps

 if (atomic_commits) {
  FlushFileBuffers((HANDLE)_get_osfhandle(file->_file));
 }

    would be ok?

Thanks,
John Goehringer
