Hi Stanley,
thanks for the fast response. I completely agree with you. However reality
often looks different. Often storage is used without any structure. Or it
is used sub-optimally because the developer decided "it is the best to do
so". Rewriting takes too much time... i guess you know that from
experience.
For instance a custom written revision tracking system which creates a
separate directory containing the compressed file FOR EACH REVISION OF THE
FILE.
So i am facing a directory with approx half a million sub-directories
(growing in number!) each containing one single file. Running
non-parallelized takes ages (no wonder why).
