I am trying to network computers with airport to transfer some files (about 400MB), but the transfer is so incredibly slow.
I turned on file sharing on one of the laptops, the went to Connect to Server on the other. Then I dragged the files over, but it said it is going to take about 4 hours to do this.
The internet is working fast on both powerbooks, so I don't know what the problem is. I know that I can transfer with target disk mode, but I don't want to do that.

AP extreme or just AP. The older airport is pretty slow really when Xfering files. remember older AP is 11 mb a sec and you never get that. If you are useing AP extreme then it should faster 54 mb a sec. but still kinda slow. Consider that firewire is 400 mb a sec, and firewire 800 is 800 mb a sec.
PLease correct me if I'm wrong everybody.

With some loud music + a friend to chat nearby you can get alot done. - but jezz, I'd avoid it if I had the choice---- If only real people came with Alpha Channels.......:)

Restart your Base and try again. If it speeds up, make sure you update the Base to the latest firmware. If it keeps getting slow until you restart it, your having interference problems and should try switching the channels the Base is on.

Close, kinda.
The old airport transfered at 11 Mb (megabits). We have later been told that in reality this is about half because of overhead and what not. So we are looking at about 5Mb/s. That equates to about 610 KB/s (kilobytes).
Airport Extreem is about 25 Mb/s realworld, which equates to about 3 MB/sec.
So here are the theroetical throughput values. (note you will never get values these high in the real world because of things like overhead and drive speed).
10 Mb Ethernet = 1.2 MB/s
11 Mb airport = 1.3 MB/s
54 Mb airport = 6.6 MB/s
100 Mb Ethernet = 12.2 MB/s
400 Mb FireWire = 48.8 MB/s
800 Mb FireWire = 78.1 MB/s
1000 Mb Ethernet = 122 MB/s
So as you can see, airport is pretty slow for transferring files, but it has more than enough bandwith for internet (as internet doens't even come close to hitting the ceiling)
If you want to transfer files, quickly, your best bet is target disk mode.

Also keep in mind if you have WEP enabled (which you probably should) that it adds a lot of overhead.

I had a similiar experience with backing up files with Appletalk over an Airport connection. It was painfully slow, to the point where it was just much easier to connect via ethernet and do the backup. One day, I went over to a friend's place and I copied a large file off of his FreeBSD box via ftp wirelessly. It was pretty darn fast. Went back to work and dumped the Applescript/Appletalk backup and instead went with scp in a shell script. MUCH faster.
I recommend doing wireless transfers via the terminal. Appletalk must have some enormous overhead. Hope it helps.
