Hi all, actually having a openSUSE 11.3 server installed, we face a strange trouble.
Each samba transfer ( cifs, smbfs kde or gnome, or from xp/w2k3 ) doesn't goes more than 25MB/s If we start 2 transfer the 2 are running at 25MB/s max.
Doing other network transfert (bacula, nfs, ftp) run all at the gigabit link limit of 125MB/s in read or write. (disks can run at ~350 Read write at the same times)
I've exported the sysctl -a param here http://susepaste.org/90797401
I'm asking here first, as many posts and examples are talking about tpc window or other kernel trick.
For samba : tests have been made using or not using socket option line. and that change throughput but only in range of -+4MB/s
Any ideas ? Hmm, it may be unrelated but what filesystem are you using? I'm just wondering if this might be a similar issue as in https://bugzilla.novell.com/show_bug.cgi?id=595999 Your problem looks different but I'm asking just in case...
