Help. File transfer and connection speed to our Xserve are painfully slow from newly purchased iMacs. The Xserve is only used as a file server, its running 10.4.11. The problem seems to be only happening on brand new iMacs running 10.6.3. When connected either over afp or smb copying files is many times slower than usual. Other machines on the network running either 10.4 or 10.5 have a normal connection speed. To try to rule out OS incompatibility I connected the new iMac running 10.6 to another computer running 10.4 over the network. The file transfer speed was fast as normal. So it seems the problems lies with the X serve (maybe). The afp logs either access or error don't show anything unusual. One thing that did look different was when the imac was connected to the Xserve the user had its id listed as its IP address. The other machines connected, had the id of broadcasthost. I also noticed that when connected from the new iMac I can only see one of the mirrors. When any other computer connects both mirrors are shown. Tried a restart of the Xserve but the problem persists

Thanks in advance for any advice

Since your xserve is running 10.4, I would assume it's an older xserve. This would be the issue. Your network can only go as fast as the machine sending (hdd read speed) & the machine receiving (hdd write speed).

I'm willing to bet the bottleneck is the old xserve.

On my network, which is Gig, our xserve is new, and my laptop is new, I can max out transfers at around 90-110MB, depending on the file(s).

Doing the same on our old G4 server, it would max around 25-30MB

Did you miss where the OP wrote "Other machines on the network running either 10.4 or 10.5 have a normal connection speed"?

Server upgraded to 10.6 SL. Problem persists for new 10.6 imacs. Upgrading also made the afp connect to leopard computers slow as the new ones. Still looking for a fix if anyone knows.
Thanks

Any further news on your problem?...

We seem to have exactly the same problem.. Our NEWEST member of the family portable running latest Snow Leopard is struggling with AFP occasionally... and displaying strange slowdowns despite it being a pristine (clean) machine. Where to look,.. what do do ?... arghh.

A slightly related discussion is here: http://discussions.apple.com/message.jspa?messageID=11993996&tstart=0
