(this thread came up in searching about the problem myself, so joined to post this, hence the 'broken' threading, I expect:)

I can confirm this; I'm seeing exactly these symptoms where the linux box running netatalk is running natively, not in VMWare. VMWare server is *installed* but only running in the sense that the vmnet interfaces are active.
Which begs an obvious test... There's no change when I kill the vmware networking (and all other) services. It still reckons it's going to take 24 minutes to transfer a file a little under a gigabyte.
Although, in fact, this thread does present a likely temporary workaround; to install a linux with an older kernel into vmware and use that to serve my content. :-D
That Linux system is Ubuntu Gutsy all up to date on amd64.
rachel@mab:~$ uname -a Linux mab.local 2.6.22-14-generic #1 SMP Tue Dec 18 05:28:27 UTC 2007 x86_64 GNU/Linux
netatalk 2.0.3-6ubuntu1 (built with ssl)
I'm getting between 500KB/s and 1MB/s on copies from that machine to a couple of macs on the local (gigabit) LAN. (They're both Intel macs running Leopard all up to date.)
Conversely I'm getting between 20MB/s and 40MB/s on copies from the macs to the netatalk server. (The variance is between the macs; one of them seems to be copying about twice as fast as the other probably due to issues of their own, but both clearly show that reading from netatalk is heavily crippled.
NB: I also posted this as a bug on ubuntu launchpad here:
https://bugs.launchpad.net/ubuntu/+source/netatalk/+bug/186327
But I noticed your precise question and thought I'd answer it. Don't know how useful I can be in here but I can certainly respond to requests for further info.
