BebopBlues Posted February 18, 2007 Share Posted February 18, 2007 For unknown reasons in OSX, network transfer from a Windows shared volume to the Mac is ridiculous slow, less than 10mbit/sec. Yet when transfering from the Mac to Windows, speed is normal and fast. Also when in another XP machine, I can transfer files from and to the OSX machine with no speed problems. So its only when I'm on the mac and accessing files from the PC's shared volumes that it is slow. What's odd is when I'm downloading something with fast speed (150k+/sec) with firefox or safari, then the network transfer is fast. But as soon as the download is done, the transfer speed is slow again. I've already tried every Yukon and Samba fixes that I could find on this forum and failed to find a fix. I have an Asus K8V-SE Deluxe with built-in Marvell Yukon 88E8001 and running Jas.10.4.8.AMD.Intel.SSE2.SSE3.PPF1.Defiant using the 10.4.6 Samba fix (the 10.4.7 Samba fix from Moto.X does not work). Is this a network adapter driver issue or a samba issue?

tuxuser33 Posted February 18, 2007 Share Posted February 18, 2007 (edited) maybe helpfull in german! look for socket options http://lug.krems.cc/docu/samba/appb_02.html http://www.macwindows.com/tiger.html#SMB1 Edited February 18, 2007 by tuxuser33 Link to comment https://www.insanelymac.com/forum/topic/42784-slow-network-transfer-from-windows-shared-volume/#findComment-306195 Share on other sites More sharing options...
frizbot Posted February 18, 2007 Share Posted February 18, 2007 (edited) Honestly, I don't know. I say its an OS X issue. It just seems to be a terrible SMB client. You can try sharity and mount_smbfs, that can help. With OS X86, I found 10.4.7 couldn't use Samba with my network card, but 10.4.8 was better. Samba is the easiest for a mounted network filesystem, but it really isn't ideal. I wish AFS was easy, or NFS4 was supported, or SSHFS was good, but they all suck. Samba options are available, lots of things to optimize and change. I'd post some info, but it usually doesn't help much.

tuxuser33 Posted February 19, 2007 Share Posted February 19, 2007 (edited) Yes, I agree. Apples SMB-implementation is odd. Example: source Mac--> destination shared folder in Windows After disabling the firewall the speed was increased from Bytes/s to MBytes/s. Sorry ! I was wrong. A copy of 3000 small files (sum app. 45 MB) takes 10 minutes; gave up with firewall activated. A copy of one file of 900 MB takes 2 minutes with firewall deactivated; 3 minutes with firewall activated. That has to deal with authentication I think. Maybe authentication for each single file, eats all performance.

BebopBlues Posted February 19, 2007 Author Share Posted February 19, 2007 Its seems to be an OSX samba problem. For example right now when I just booted it up, the network transfer speed is fine. But if I reboot, it might go back to slow again. This has happened before and I'm clueless what the problem could be. I can try mount_smbfs, whats the best way to mount with it? Can I make an apple script to mount? I guess I can also put the the line in /etc/fstab also.

frizbot Posted February 19, 2007 Share Posted February 19, 2007 (edited) I don't remember if OS X has an fstab, I think it was just a dummy file. There's a file in /etc though that one can customize to run a bash command on boot. I really don't remember what it was though, sorry. It might be easy to make a startupitem, but I did the mount_smbfs with an applescript. "do shell script "mount_smbfs -w WORKGROUP //myuser:mypass@serverIP/share"" or something like that. There's samba releases for OS X, but I never could compile them or otherwise install, no idea why. It was just constant work fixing compile errors and missing dependencies. Fink could help. I had a theory that OS X Server had a proper Samba setup and the Client was hobbled somehow, but thats just me being annoyed with the bad samba implementation in OS X. There really are configuration options that could maybe help. readraw=no , oplocks=no , the socketopts, something about large blocks. I occasionally get some samba error where the Windows machine kicks itself off the server and gets a -22 error (IIRC), so occasionally I look into the configuration options and other mountable filesystems. NFS using WSFU is a huge pain in the ass with username mapping. SSHFS is possible on windows with 3rd party tools but it isn't fast and connections can be dropped, though it has the most potential. AFS just plain didn't work for me. If you get this fixed somehow, do tell how. I still get terrible performance over Samba but I need a mountable network filesystem.

BebopBlues Posted March 22, 2007 Author Share Posted March 22, 2007 If you get this fixed somehow, do tell how. I still get terrible performance over Samba but I need a mountable network filesystem. Just an update, the slow network transfer with samba somehow went away. It now transfer normal LAN speed. I have no idea what I did to fix it, but I'll try to list the changes I made. - I reinstalled JAS 10.4.8 AMD SSE2. I still get the "alias missing" error when trying to connect through samba. - Applied the SambaFix for 10.4.6. Samba now connects, but slow network transfer still a problem. - Installed Parallels virtualization, it also installed a bridge adapter in the Network system panel. - Added a second network card, D-Link DGE-530T, configured it to work, still slow network transfer. But for unknown reason, the Parallels adapters disappear in the network system panel. - Updated Compressor and Apple Qmaster using Software Updates. - Installed latest Shapeshifter. At some point between the the last two steps, I noticed Samba Network Transfer is fast like normal LAN. Not sure if any of that helps, but somehow whatever happened, my samba problem was fixed. Let see if it continues to do from now on. Its the only problem that I couldn't find a workaround for since I need access to my Windows Shared volumes.

MyghKaR5b Posted March 22, 2007 Share Posted March 22, 2007 I have terribly slow transfers across my gigabit network on my hackintosh, will have to look into these solutions.
