Hi, I have samba-3.0.11-1 on a Red hat ES 2.1 box. I also have a Win 2003 Server Domain Controller, to which my users should autenticate. My files are all in linux machine (+ also apache, mysql etc) I have also an Access mdb that could be open by several user at same time, based on linked mysql tables. Opening certain masks in access is veryyyyyy slow, so I try to create another share, accessible from everyone, and put there the same db. Well, this way Access works fast. I'd like to know which is the reason for the performance difference. Here my samba conf Thanks # Samba config file created using SWAT # from 0.0.0.0 (0.0.0.0) # Date: 2005/02/18 18:57:26 # Global parameters [global] level2 oplocks = No lpresume command = lpc release '%p' %j remote announce = 10.243.255.47/mydomain printing = lprng dns proxy = No hide files = /*.GID/*.gid/*RECYCLER/desktop.ini/DESKTOP.INI/ encrypt passwords = yes queueresume command = lpc start '%p' socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 max log size = 1000 directory mask = 02770 admin users = administrator preferred master = No lock spin count = 100 security = DOMAIN ldap ssl = no printer admin = administrator queuepause command = lpc stop '%p' lppause command = lpc hold '%p' %j server string = Server Dell workgroup = MYDOMAIN message command = /bin/mail -s 'messaggio da %f on %m' root < %s; rm %s lock spin time = 200 log file = /var/log/samba/log.%m netbios name = DELL_ES create mask = 0664 [archivi] path = /home/ei # valid users = +mydomain # write list = @mydomain read only = No guest ok = No # oplocks = Yes level2 oplocks = No # veto oplock files /*.mdb/*.MDB/*.dbf/*.DBF/*.pst/*.PST/*.dat/*.DAT/*.idx/*.IDX/*.vix/*.VIX/ [test] path = /home/test writeable = yes public = yes guest only = yes
