Download, unzip and run our Automator Application: http://www.mat.ethz.ch/services/it_s...ed_ack.app.zip
and samba work very fine!
This application does the following:
* show an info panel
* ask for an administrator account and password
* sets net.inet.tcp.delayed_ack=0
(This tells the TCP stack in the kernel to not delay packet acks.)
* create the file /private/etc/sysctl.conf with content net.inet.tcp.delayed_ack=0.
