Hello, I sent the following message to the Debian folks.
They don't think that the Debian packaging could be responsible for the issue described there. > Well, I'm not completely convinced that we will have very useful input > for you.

I must say I didn't try to compile it from the upstream sources for many reasons. Anyway, I think that there is poor chances for the issue to be related with the Debian package. Thank you in advance for your advices ;) Happy new year ! (yeah, it depends on where you are in the world !!) Fabien -------------- Hello, sorry to write directly to you, but after long hours spent trying to solve this strange problem, I thought it could be handled better by speaking directly with you. I hope I'm not wrong... While testing samba speed on my file server, using a fully tested gigabyte ethernet connexion, I encontered some very strange performance problems. I had big speed differences when using samba locally, or via the network (gigabyte). "Mb" stands for Mbytes. * My server config : - AMD X2 4200+ - 2 Go RAM - 4 x 500 Go --> RAID5 - Gigabyte connection - Debian ETCH - debian package : Samba 3.0.24 (I also tried to backport the testing version => 3.2.5 but the results were exactly the same) * My samba share folder is a partition of my RAID 5 (reading : 170 Mb/s & writing : 90 Mb/s). * Here are my benchmarks (nearly the same from Linux or Windows) : - Reading via ftp on the server (no samba) from a Gigabyte client : => 120Mb/s - Reading on the samba server from a Gigabyte client => 35Mb/s - Writting via ftp on the server (no samba) from a Gigabyte client : => 90Mb/s - Writing on the samba server from a Gigabyte client : => 40Mb/s I also noticed that if I try to read/write on the samba server from more than just one client, the results is exactly the same : the server bandwith limit is 35(up)/40(down) Mb/s. /!\ When I mount the samba partition localy (on the server) I can read at 115 Mb/s or write at 90 Mb/s, which is the good behavior. I tried MS Windows and Linux (etch) smbfs clients. I did a lot of testing, using a 1Go RAM disk on both sides to avoid disks problems, and got the same test results. Do you think that the problem could come from the Debian package ? I investigated google a lot and found very few people reporting this strange behavior (mainly from ubuntu forums). I am pretty sure that several (every ?) people, at least from debian, are concerned. I think that they just didn't notice the speed problem (35Mo/s is still quite nice to be noticeable). I found some people trying to tweak the samba buffers : they only got a little better speed (+ 5Mo/s). My smb.conf file is attached. Thanks for your help. Cheers, Fabien
