Using Mac OS X 10.2:
I am currently doing two downloads. One with the "ftp" command line utility, and the other with Fetch (i just downloaded it). I notice that the unix cmd is downloading the file faster AND using *much* less cpu. Here is the output from "top":
974 Fetch 4.0. 42.9% 8:03.40 3 85 164 3.86M 14.5M 11.8M 108M
398 ftp 0.0% 0:35.93 1 10 27 188K 400K 544K 2.35M
395 Terminal 5.9% 7:03.60 5 77 391 2.53M 11.1M 9.04M 51.4M
I understand that it has a graphical user interface, so it's memory and cpu usage will be higher than a text only interface, but the difference is staggering.
Is this just how efficient Carbon really isn't?
Notice the CPU time: Fetch has downloaded more data using 35 seconds of cpu time, than Fetch has with over 8 minutes of cpu time.
I guess a valid comparison would be between the data download thread of fetch compared with the ftp command.....
or should i look for a different ftp client with a native cocoa interface that will be more efficient...?

In this comparison Fetch is paying for some design decisions that made good sense under the Classic Mac OS but don't under OS X. I have been working to correct those issues, and expect further improvements in future releases.
