[Bioperl-l] Speeding Up File Access

[Johnny Amos]

Hello,

There was a recent article at PerlMonks.org about speeding up file IO:
http://www.perlmonks.org/index.pl?node_id=344087

One thing that caught my attention was the use of the :raw pragma on 
filehandle creation to explicitly prevent handling of Unicode text.  In the 
example given this cut file IO times in half for a 3 GB file.

open (FH, '< :raw', $filename);
instead of just:
open (FH, '<', $filename);

I tried to look at Bio::Root::IO to see if an option for using this (or an 
equivalent) was already implemented, but couldn't see one.

Is this something worth submitting a patch for?  Would it be useful for 
things like UniGene, LocusLink, BLAT, and Blast parsers or can these files 
contain Unicode in them somehow?

Johnny
