Why is logging into a pipe considered a waste of CPU?
The log parser throws away some data, aggregates the rest and then writes
it to a remote database. The "tail -f" approach would waste lokal disk i/o
by writing data unnecessarily to disk which i would then have to read again
with the script.
Why is this considered more efficient than handing the data directly over
to a script?

Dennis
