I sent him an email last week or two ago asking what was his ./configure string and setup stuff. As I mentioned earlier, no response. xx(

I have no problem using Netatalk 2.1.6, although if I could use 2.2.4/2.2.5 I would. One exceedingly interesting point is a line from my speed test:

Mac mini Netatalk 2.1.6 | Duo 2300cTB 7.6.1 | AFP over Ethernet | 437.7KB/sec, 3.50Mbps | 37.8KB/sec, 0.302Mbps Slow! |

If you look at the other speeds for AFP over Ethernet in the Data Transfer Rates section, it is abnormal to a rather high degree.
