I have a big data file need to write to NFS directory which is mapped under a Windows system. I had 2 different approaches to achieve this.
I wrote (using the “save as” command) from the app directly to NFS. I first wrote to a local drive, then copied the file to NFS directory. I didn't do accurate statics, but it occurs to me approach is definitely faster, and seems I cannot find a reasonable explain for this phenomenon, anyone got any ideas?
Say I have a big file (600 MB), if I directly save it to NFS, it will be slower compared to I first save it to local drive then move the file to NFS, why is that?
