Hello everyone, I could really use some help trying to diagnose a tricky issue within the domain I have set up.
I am using samba-3.0.28-1.el5_2.1 and openldap-2.3.27-8.el5_2.4 on a server running Centos 5.1. I have everything working properly within the domain, users can log in, netlogon scripts are run, their profile is loaded, etc. I have been extremely happy with this software and can't thank the makers enough - great work! The issue I am having is with the speed of profile loading/saving. This network is hosted on a Gigabit Lan - this is a classroom environment where students must save large files in their profile (virtual machines actually = ~3-4GB per profile & will grow...). I know the best option is to save the work elsewhere, like their mapped home directory, but it would be highly inconvenient to copy the VM back and forth every time they wanted to use it (although much faster than the logon/logoff speeds). Let me elaborate: I have done speed tests transferring files and directories directly to writable shares. I have monitored the network speeds with iptraf on the server while downloading/uploading a 1 GB or file or large directory on the relevant interface (there are 4 local interfaces) and these are my approximate results: DL from Samba Share: 300,000 - 400,000 kb/s UPL to Samba Share: 300,000 - 400,000 kb/s These speeds are GREAT! I was blown away! -- But then take a look at the speeds at which the network operates when loading/saving a user's profile while logging in/out: Profile Logoff: 50,000 kb/s (a ~3GB profile takes roughly 10 min to load) Profile Logon: Not Tested - but observed to take about 10 minutes So my dilemma is that, while the networking is functioning exceptionally well in all other areas, it just takes so long to login/logoff! The users need to have roaming profiles (they do switch machines sometimes) & I would like them to be able to store a lot of data inside their profile without speed becoming too much of an issue like it is now. I have messed around with a few tweaking options in the smb.conf file, but they have not helped so far. So, I just went back to using TCP_NODELAY. I have turned off oplocks as well. I am not sure how to proceed now and I am pretty much taking random stabs in the dark with this issue, any help would be GREATLY appreciated!
