Very interesting! Thanks for the new idea!

I lost my server connection for some reason and so I tested this on my laptop and I do see a very good improvement with the your modification.

update: corrected <> with $_ per pijll post 

C:\>perl -lne "BEGIN{$,=','} print+(split',',$_)[0..14] " > junk

[download]
this finishes in about 14 seconds.... corrected timing

C:\>perl -lanF, -e "BEGIN{ $,=\",\"} print @F[0..14];" numbers.csv > j
+unk

[download]
this takes about 18 seconds

I don't have a timing utility in Windows so the times are just wallclock times.

I guess windows is faster because the process run at 100% CPU (or whatever is required i guess?). On the UNIX servers the process might be more time-shared?

My laptop is 1.6G Centrino/1GB Ram/perl, v5.6.1

cheers

SK Update: Thanks pijll, the time it takes to run your version of the code is almost same as the one that uses -n.
