but the stupid dd-test does not reflect reality

for most workloads /tmp is not touched most of the time
in any way - keep in mind that applications needs to
be changed to usr /var/tmp if they expect really
large temp-files compare the real benefit with the
complete work and bugreports for forgotten packages
trying to store a iso-image and such things on /tmp

the benefit for the normal workload has to be compared
with the overall work for a feature and not only
some generic tests
