erm... on my Classic Amiga I have a 68060 overclocked at 66Mhz. . . . .. .

tested just now and it takes about 2 minutes to write a 262 Mb file, however
thats depends on the IDE controller, Im using the A1200's default controller
with transfer data of about 2.5Mb/s (Im talking of a 1992's computer :)

hmm, no more laughts folks! ;-D

right now Im using btget, also running my browser, my emailer (ofcourse, Im
writing this ;), a filemanager, Apache, samba, and some other daemons..

can you deduce my current CPU Usage? I can guarante you 20-30%! :)

The only "problem" I have with btget is due lseek()... since AmigaOS's seek
functions lacks of auto-expand feature I needed to implement that thing..
just allocating a chunk of mem of ~10mb and filling the file with zeros until
the offset desired, and Im almost sure the big problem here is my lseek()
implementation which isn't properly optimized...

however that isn't a great problem for me, since the 700Mb files I download
aren't fillied in one step (except when I restart btget after few mb
downloaded..), honestly I can't see big problems right now, Im so happy to be
able to downloaded torrents for first time on my Amiga :-)..




Kind Regards
