Hi there,
Yesterday I reseated the network cable between my server cupboard and
my desk, and it now lights up on the switch by my desk as gigabit. But
a file-transfer today is slower than I might have hoped.
I'm not ruling out the cable, because it's pretty beat up (but the
switch *is* lighting up as 1000), but how do I determine, please, that
the Linux server at the other end is recognising the NIC and
negotiating as gigabit speeds?
The hard-drives on the server are using an older PCI SATA card, and
the NIC is also PCI. But I would have expected it to be a bit faster
than 100Mbps.
Any estimates over what kind of speed I should be seeing for large
file-transfers over Samba? Wildly ball-park is fine - I wouldn't
expect a 10x speed increase, but maybe 2x or 3x - 4x would be great!
I'll be testing between my Macs (both on the desktop switch, ruling
out both the Linux box and the suspicious cable) later today, I'd just
like some ideas of where I should be starting from.
Right now I'm seeing 10 gigs of .mp4 files (1gb - 2gb per video file)
taking about an hour - that's about what I'd expect from old 100Mbps
networking, not this shiny new stuff.
I'm not seeing any difference commenting & uncommenting "aio read size
= 1, aio write size = 1" (separate lines) from /etc/samba/smb.conf and
then running `/etc/init.d/samba reload`, but maybe I shouldn't expect
that to make any difference on an existing transfer. I just don't want
to interfere with this right now - I just want to copy as much as
possible on to my laptop before I go out, and I'll take a look at this
performance issue when I get home.
Thanks in advance for any suggestions or pointers,
Stroller.
