[Samba] samba v3 slow with 'security = server'
We were running samba v2.2.x with the 'security = server' option and everything worked wonderfully. We upgraded to samba 3.0.10 with the same configuration. Everything still works but it's very very slow. Opening a file can take 15 to 30 seconds or more. I changed the security option to 'user' and everything is fast again. Clearly something has changed between 2.x.x and 3.x.x to slow this down immensely. Is there any way we can run with security set to server but cache the results of the server conversation? Am I missing a new option that can set? Would 'security = Domain' help? or will it suffer from the same issue.

Anthony, I don't think changing authentication to 'security = Domain' would help a performance problem. I'd make sure that you're not running into memory, disk or network congestion problems. I forget the number but there is a recommended amount of memory/user so knowing the number of connections is important. Memory usage can make a huge difference in a Solaris environment. Make sure there hasn't been any changes in usage either. There are lots of areas that could affect this but those would be my starting points. spike Anthony Iano-Fletcher wrote:> We were running samba v2.2.x with the 'security = server' option and > everything worked wonderfully. > > We upgraded to samba 3.0.10 with the same configuration.
