Copying files via samba slow to start

[storageman]

30 seconds to start copy, sure wake on lan isn't on?
Try direct connections and bypass switch to test concurrent load to both PCs. Maybe your switch is the issue?

The 30 seconds wait is only the first time (after powering on the NAS)

I have it scheduled to turn off at night and back on in the afternoon. Usually the first copy to the NAS will take a while to start. After that it's fine, I can copy files for the remainder of the evening, at various intervals, without issue. And I know the disks have definitely spun up as someone is generally streaming a TV show from it at the time. Pretty sure it's not the switch, I had the same issue with previous switches, and this one is a relatively new 16 port netgear. Don't have issues copying data between any other PCs on the network.

I have been experiencing something similar, however in my case, the slow to start transfer only presents itself after a restart.

That sounds exactly the same as my problem -first transfer after a restart is almost always slow to start.
