R: [Samba] High CPU utilization with samba2.2.5 on HPUX 11.00

[Usai, Maria Grazia]

Note that the problem arises only by scanning subdirectories with a large number of files ( 3.000 files and more ).

Oggetto: [Samba] High CPU utilization with samba2.2.5 on HPUX 11.00



Hello, I need some help for a strange problem. 

I have an HP L2000 server ( 2 CPU and 2 GB RAM ) with HPUX 11.00 and with samba 2.2.5 installed 
Below my smb.conf: 

workgroup = <my-w2k-domain> 
netbios name = <my-server> 
interfaces = <my-ip-address> 
bind interfaces only = Yes 
security = DOMAIN 
username map = /usr/local/samba/lib/smb_users.map 
        ... 
[my-share] 
comment = <my-share> on <my-server> 
path = <my-path> 
read only = No 
dont descend = ./lost+found 

The others parameters are set to default. 

The size of my-share filesystem is 170GB. 
Analyzing the server performances, I observed that when I access to my-share from an w2k workstation  to list its contents whit windows explorer, all works fine and the serverv cpu utilization is very slow, but, if I access to my-share with a C program that recursly scans my-share performing a "stat" for each file on the share, the smbd process consumes the 99% of server CPU resource!! 

Can anyone help me to resolve this problem? 
Thank's in advance.
