Leopard: problem with home network
Hi, I've made a clean install of leopard but since putting back together my home network I'm experiencing seriously slow speeds, that make it impossible to stream music or video from the xp machine (it starts, stops and the lockup).
The network runs wired with cat6 cables and gigabit router.
Needless to say, under Tiger speed was always excellent.
I tried disabling the firewall on both ends, resetting nics but no luck.
Anybody with a wired network experiencing any of this? thanks

Internet connection, through ethernet, works without problems on both computers.
...is there such thing as a CAT6 cable?
yes there is - but it's backward compatible to cat 5
the problem sounds like a messed up router.
i would check if the settings on the router are ok (like the "full-duplex-thing").

I would say that sadly, it does not "sound like a messed up router". Given that the only thing changed was Tiger --> Leopard, it sounds like a messed-up Leopard.
To the O/P: what, if any, third party applications do you have installed in OS X?
How many machines do you have on the network and what OSes are they running?
On the lan I have one xp pro sp2, one xp home sp2 and one leopard.
I thought it could be a problem with leopard but around the boards I just keep reading about wireless problems. I guess I'll just have to wait and see if something comes up with leopards updates.

I thought you said you were using a wired connection?
Can you verify the speed of the network by copying files from one of the PCs to the other?

allmost every time apple releases a new os (or even an update), they make small (undocumented) changes that can effect stuff like this.
just my 2 cents
macbook pro with aiport extreme (802.11n) router trying to stream from mac mini, both leopard upgraded.
slow as hell.
macbookpro via wireless and mini is wired
btw, do you know how do you connect to you shares (smb?)

Yes I am on a wired lan, but browsing for similare network problems I could only come up with wireless related issues.
Copying files between xp boxes is fast with no lockups.
I could connect by using ftp though, but i can't connect via ethernet cable or just plain finding an icon and connecting wirelessly, just ftp wirelessly. gay.
that being said, i got a new imac yesterday which shipped with tiger and leopard on an update dvd. i first booted it up and played a bit around with tiger and got good wifi and wired gigabit speeds. i then upgraded to leopard and i got the same problems: wifi speed is decreased and even worse, gigabit ethernet is really, and i mean really really slow! and no, its not the rest of my gear, as it works fine and worked fine before the update. so anyone having a solution for that? i am getting an average of 3mb over wired gigabit... and i should see an average of 30mb to my nas and other computers....
ipV6 off, flow control off (gigabit eth0), jumbo packets etc. all without any luck.
I came across a problem reported with regard to tiger, some ack packets not being handled by some nics and therefore causing problems. it seems that those smb.conf settings used for tiger are no longer correct on leopard? i tried that and i can confirm that nothing has changed - unfortunately.
just for the record: other xp boxes get stellar speed of the wired and wireless network - no problems there and as i said, it was working fine with tiger before - the network configuration hasn't changed.

I read reports of various Windows networking settings not sticking properly in OS X's default "automatic" network location. If you create a new location, and make sure stuff like the Workgroup is set correctly, does this make any difference?
Do you live near an Apple Store so you can go and speak to a genius?
Also, you could try the macosxhints forums to see if anyone over there has any bright ideas.
Please keep us posted with any progress you do/don't make.
I would say it is a mix of a crappy cifs/smb AND network driver implemention. Here is why:
if i connect to my NAS (keep in mind that this worked with tiger flawlessly) via SMB or cifs i get very poor performance - something around 3-4mb average, maybe, on wired gigabit. If i connect to the same nas via the same physical connection through AFP, i get an average of 12-15 mb/s...3-4 times faster! i did that a few weeks ago when still on tiger and i noticed an increase in speed as well... from 30 mb/s average to 32mb/s... no big deal.
So that tells me that
a) afp works better or is better implemented - dramatically better on leopard than smb
b) if i compare the same hardware performance on tiger and leopard under similar circumstances, then tiger is about 10 times faster on a gigabit ethernet than leopard is right now (on smb that is).
so there is something going on... and i can only hope that Apple gets their stuff together soon.
