Current scripts create and delete multiple files over NFS. I have been told that this is the problem, so was thinking if the run directory the script ran in looked like a single file to NFS then I might alleviate the problem.
I should add that we have hundreds of these scripts working in their own run directories but all over NFS at any one time, and we have a bottleneck due to the creation and deletion of many tens of files for each run directory.
I have since found http://code.google.com/p/fuse-zip/ that I will investigate. Could someone share their experiences with this?
