multi user access to 1 data file

[dkwok]

I am running v2.0.7 and have set up a network drive for an accounting ledger system. The software is called MYOB and is quite popular in Australia. This is the first time I have to deal with multi user access to 1 data file. 

My setup is:

Global

oplocks = yes
socket options = TCP_NODELAY
socket options = IPTOS_LOWDELAY

[MYOB]
path=/home/office/MYOB
force group = office
directory mask = 0770
browesable = yes
writable = no
readonly = no
creat mask =0770

The MYOB program is executed local at workstation and only access data through the network drive. When only 1 workstation accessing the data the performance is quite normal. However, as soon as another workstation logged onto and accessing the same data file. The performance is not so slow that it takes 2 minutes to record a transaction.

I have relocated the same data file into a win98 machine and all workstation access it from that machine. The performance is then back to normal. So either Samba is working differently when it is in multi user mode. This is only accessing data therefore we should be talking about file locking, transfer, read and write, etc.

Please send me any pointers or tech reference in how to resolve this issue.
