Excessively slow network transfer speeds from XP to Linux…


Hey Everyone,

A little while ago I decided it would be a great idea to install Mandrake Linux 10.0 on my laptop and use it for mobile computing. The results have been outstanding and thus far I have been extremely pleased with Linux as an OS. ;-) I am not a very big Linux Buff (read: I am highly Linux Inept) and have since run into a problem that I just haven’t been able to work out…

A little while ago I was at a friend’s house on his network. I was using Samba to browse through his shares, grab files, etc. The browsing was easy, and the transfers where fast. Later (on or about a week from then) I went to another friends house and noticed that while I was still able to browse his shares (both friends where running Windows XP Prof.) my speed at transferring was horrid (to the tune of less than a MB a second and stalling often). Furthermore, while the transfer was in progress, my ‘connection light’ on the router would just shut off randomly (which, obviously, isn’t something it usually does).

At the time I saw it as a bit of a fluke. It had run perfectly one time and I wrote off the poor transfer speeds and horrible connection problems to my latter friend’s aging network and PC. However, after getting home, I tried transferring some files from my Windows XP desktop to my Linux laptop. Unfortunately, the problem persisted. Not only that, but it has persisted on a variety of networks.

I am, well, not very knowledgeable in this field and would greatly appreciate any help that some of you would be willing to offer! I would hate to think that my built in Ethernet device somehow got damaged and would hope that this problem can be fixed on the OS or software side of things. Thank you in advance for your time and recommendations on how to alleviate this dilemma!

-K

there are a few tweaks for the samba server but my practical knowledge is that this often is a problem within microsofts packetsize and other "ms-futures".
you may put
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=8192 SO_SNDBUF=8192
into your smb.conf and do some benchmarking before and after adding an option. these tweaks won't give better performance on every system and it's not said that it will give any increase at all !

also check you logfiles since drastic low troughput could also (likely) mean a misconfiguration.

sl mritch.
