Can anyone shed any light ( or offer dome diagnosing tips) on why I am seeing a considerable time delay in opening and writing back to excel files on a Samba 3.3.4 build where as the same file on an earlier build (2.2.8.a) does not exhibit the same latency ??? - 11 seconds as opposed to 3 seconds. The problem does not seem to be as pronounced with other file types though it is still slower. This problem has been plaguing me since I upgraded samba to a new host and went production on it and NOW I am receiving a barrage of complaints from admin staff with the "why did you break it" ? underscore !! At this point I have ruled out the obvious. Hosts running the builds are on same network, storage is faster on the new build, same ver of excel, same file (7mb) accessed from same machine. Newer build is running on substantially faster hardware, and storage BUT is authing against an ldap backend as opposed to /etc/passwd Any suggestions are appreciated !!

You might want to get debug level 10 logs from the old and new versions and compare where things start being different. Jeremy
