Hi, I have an NT machine running an application which refreshes a text file every minute or so with fresh data. The directory containing this file is shared so that I can do an smbmount. I have a linux machine which runs a program to interpret this file. When the program starts up, it does smbmount of the remote directory. I am able to see the file but there is a very visible propagation delay. I mount the same directory on another NT machine and I see that the file change almost instantaneously while the linux machine seems to take upto 2 seconds longer to refresh the contents of the file. The application is very time sensitive and needs to synchronize this file change event with other events coming through the audio input. I set up TCP_NODELAY in smb.conf but that did not help. Also tried setting fmask=2755 in the smbmount options (as per smbfs.txt file). Don't know what else to do to eliminate the additional delay. Any pointers?? Thanks in advance, Sudheer
