The best thing should be to launch every single test code. At the end you sill find my two tests. I need raw data, so i must re-read the test file. They work well under the new beta (1.2.5) in my tests beta are twice fast on this sort of code. Here are my test where you can seel the result of system/stats and allocated memory increase: Rebol - Celeron 333 RAM 128 Mb Window 98 first edition reading data : 0:00:00.11 memory allocated: 6465424 Scott : 0:00:02.74 memory allocated: 10714448 Carl : 0:00:02.58 memory allocated: 12752096 Romano : 0:00:01.54 memory allocated: 15060400 Romano-int : 0:00:01.7 memory allocated: 17671880 Joel : 0:00:01.49 memory allocated: 22394888 got same results done By other test i noticed than Joel code use 3 Mb memory more than others tests. -----------code----------- ;; Romano -- parse sort ;; ------------------- data: read %../public/ report-item/start "Romano" sorted-data: [] parse/all data [ some [ copy num [any " " to " "] copy rest thru newline (insert insert tail sorted-data num rest) ] ] sorted-data: sort/skip sorted-data 2 report-item/end "Romano" write %sorted-data-romano.txt sorted-data unset 'sorted-data recycle ;; Romano -- parse sort int ;; ------------------- data: read %../public/ report-item/start "Romano-int" blk: [] parse/all data [ some [ h: any " " copy num integer! :h copy rest thru newline (insert insert tail blk to integer! num rest) ] ] blk: sort/skip blk 2 report-item/end "Romano-int" sorted-data: copy "" foreach [x x2] blk [insert tail sorted-data x2] write %sorted-data-romano-int.txt sorted-data unset 'sorted-data recycle ; for next texts: data: read/lines %../public/ -----end of code ---- --- Ciao Romano
