I've just entered the wins server in smb.conf, i will check tomorrow if the speed will go up. I doubt it, but hey if i don't try we certainely won't know :) WINS is only beign used as a nameserver for samba/microsoft networking, so i won't speed up transfer rates or whatever. If I authenticate to a share, we have choosen for security=share and guest only=yes. I could try to change the security to our domain (i'm also a member of domain admins). But I doubt that this will improve our speeds, because it is only a matter of authentication when i access the share. Not when browsing, copying etc (correct me if i'm wrong, that's what i understood of the samba documentation). We did some extra testing with NT <> NT. We copied ONE parts directory to another nt cadstation and shared the dir. We changed our searchpathes, and loaded the assembly into memory. This was JUST as fast as unix <> unix. BUT, our unix server has a maximum network transfer rate of 5/6 mB/s (we have a sh*tty old btlan card), whereas the cadstations can get speeds of 12 mB/s! Second, the harddiscs of the cadstions are much faster, so is the cpu, it has more memory etc. AND we compared it to unix download the same assembly, but with all the other assembly directory in its searchpath. So nt was MUCH slower! It only looked faster, but the comparison was just false. NT Cadstations are just faster then our unix server. Our physical network is 100 completely switched, and 1 gigabit backbone. We are in a different subnet than the other normal workstations, and we're being connected to the 'other' network with a router. We don't get any broadcastmessages from the other network. And when the cadstation is idle, we get about 1 kB/s on the lan-card. As our btlan card won't run on 100 mbit full duplex, we now have the card on 100 mbit half duplex. Our unix stations are running 100 mbit full duplex, just as our nt cadstation. I have level 10 log files of samba, and i have captured frames on nt, but i didn't see anything strange... I installed glance today, and nfs/smb has the same transfer speeds. But samba is using 50-60% cpu time, whereas nfs is just using 5-10 %... But nfs is using almost as many disc IO/s as smb. Why would netbios send broadcast messages when viewing directories or copy files? I also did a samba <> samba test, so i copied a 100 mB file, and it took the same time as on nt. Btw we are using IBM Intellistation M-pro with win2k sp2 on it. How did you solve your problem? Because i think it's in proe, or in a system call from nt that proe uses.
