Description ylet 2007-05-23 08:24:11 UTC
i am using three computer, named A,B,C , A and B all are linux and C is windowsXP
A is a samba(3.0.25) server ip and B(kernel 2.6.21) 

B do the operations sequence 
B: mount -t cifs // /mnt/sdb
B:service smb start (share name is sdb)
and B use samba(3.0.25) and have two NIC ( and

C mapped B's shared volume 
//   to  Z:\
//   to  Y:\

now, i begin to read the same file named x.dat from Z and Y

 added speed come from these two process is very slow!

i traced the oplock and i can see the client(B) first get the pSMB of OplockLevel=1 , and get the pSMB of OplockLevel=0 after seconds.   

this means when two and more process read the same file in above box, B can not cache files! why?
