Hi all,

im accessing a shared folder on my windows machine FROM my PB... when i transfer files i get no more than 400k/sec... wireless or wired...

when i ftp files, i get 8meg/sec (wired) and 1.5meg/sec (unwired)..

so the problem seems to be with netbios transfers...
anyone encountered this/have any suggestions?

thanks all!

I've also noticed similar occurances. I take my mac along to LAN's with my PC so I can game and leech at the same time, without affecting each machines roles as well as being able to view the other machine while gaming.

Anyway... I digress.

Yes, I've noticed that with Netbios... the speed is heavily limited. I've never looked into it.

Which version of Windows are you running? I don't have these issues.

..wait, what am I saying, I don't want to try to troubleshoot Windows problems!!

Do you have problems with speed putting files onto your OSX machine from windows box?

i havent tried to copy from windows to the mac to be honest..

(note this doesnt only happen when i connect from my mac to a windows share, it also happesn when i connect to my linux shares)

i read about a configuration option in smb.conf when my mac is running a share - but this obviously doesnt apply when im connecting FROM my mac....

this is a real issue for me as im building a fileserver this weekend... hrmm...
i wonder what would happen if i called apple tech support ?

I have noticed that its only slow when coming from the PC to the Mac. But transfering file from the Mac to the PC is fine.

Its a problem with NetBIOS. I've found that it can be slow even when transferring from Winbox to Winbox.

Any ideas on how to fix the problem? It's really frustrating when I'm sitting at a LAN, and all my mates with their PC's are leeching at 10MB/s and I'm getting 500K/s

Some Google results suggest adding a few lines into smb.conf..?

Here's my speed going from my W2k box to my PowerBook:



All I've done to get this speed is specify the correct workgroup.

Considering NetBIOS hasn't been used in file transfers since WinNT4.0, I think you're barking up the wrong tree.

Windows2000 and WindowsXP both use TCP as the transport layer for SMB/CIFS transfers, and use WINS for name resolution, but with fallback to DNS.

All versions of OSX pre 10.3.5 have known problems with SMB transfers (including 10.2). It is recommended you run 10.3 with the latest patches and see if yur problem still exists.

If that fails, try connecting directly to the machine using IP rather than hostname. You may well be re-resolving names per connection, which could add the overhead.

Try and send something from windows to your MAC shared filesystem (which would then use samba on the OSX machine).

I always had slow speed from Windows to the MAC. Turns out changing 2-3 options in my smb.conf on the OSX machine fixed it.

You could put the same options I used in your Linux box smb.conf file (since you say your having issues from linux shares -> mac) so I am guessing the linux box uses samba to publish these shares.

Try the tuning the Linux and/or OS X box's Samba 'socket options': specifically the SO_SNDBUF and SO_RCVBUF options.

Hit google for some possible options..

Care to elaborate on those two-three option changes? please
