They seem to have put a ban on me or on the mere mentioning of the topic
of optimizing a certain piece of FPC code on the mailinglistm, even
though I explicitly changed the thread topic. I did not know that it is
not allowed to discuss concrete code examples (or certain types of code
examples) on the FPC list. So I re-send a copy of my latest answer to
this thread to you directly (and to the other mailing-list) which
bounced from the list server.


here is the bounced mail:

Yes, but it also runs 5 times faster on only one CPU.

The reading into the buffer does not contribute any noteworthy amount
of time according to my profiling. By FAR the most time is spent with
building up the hash table with *millions* of entries (which includes
looking up each potentially new entry before adding it).
