Hi
I am running a samba-3.0.14a und RHEL3.
If we acesse the machine with a fast raid storage wie NFS,
I can read a 2000M file in about 21s (nearly 100MB/s)
[root@rmvbs01 test]time cat 2000M > /dev/null
real 0m20.540s
user 0m0.150s
sys 0m2.680s
when I am using samba, the performance is very poor.
A Windows Clients ony reads with about 20MB/s
The same NFS unix client from above
with mount -t smbfs needs 280s to read the file.
root@rmvbs01 test]# time cat 2000M > /dev/null
real 4m42.186s
user 0m0.410s
sys 0m10.540s
Has anyone any idea what might be the reason for this big performance
difference?
Is it a problem related to linux smbfs?
I have tried serveral samba tuning parameters with no success
Is this a missconfiguration or can anyone reproduce or explain this
behavior?
Thank you very much
Hansj?rg
