I apologize  for giving wrong information again ...  :-[
The number of files is not a problem (30/40). The real deal is that some of my files have ~10^6 lines (file size ~ 300/400M) :'(
Thanks again for your help and advices!

Regards,
Paolo

How much time is it taking on the files and how many files do you have
to process?  I tried it with your data duplicated so that I had 57K
lines and it took 27 seconds to process.  How much faster to you want?
