Speed up MacOS X file transferring over network

Posted on

We had an issue with a group of MacOS X clients on a particular VLAN that were experiencing painfully slow transfers (~100KB/s) to our Solaris fileservers running netatalk (AFP). The problem was solved by tweaking a kernel parameter on the client that made it “more compatible.” delayed_ack=0 responds after every packet (OFF) delayed_ack=1 always employs […]

The program will never remove the kernel currently used (“Not removing kernel 3.10.0-327.el7 because it is the running kernel”), so you may end-up with two kernels in /boot… until you reboot and re-run the command. So the command is package-cleanup –oldkernels –count=1 […]
