These FS _should_ be better on a lot of Files in a Directory and Handling of that. Or play with the Options -R stripe=stripe_size and -J device=other_journal_device of mkfs.ext3.

RE: [Samba] performance problem with samba in any version and small files
Did you compile samba 3.02a yourself or use the RPM packages? I ran into a problem with the RPM packages on the Samba site for MDK 9.2, When I installed it seemed that the packages were not valid, they were looking for some strange name user. Some of the commands to run were not on my system either. So I uninstalled them and went back to 2.28a which works great!! Sincerely, Matthew J.

I get about 10 mb/s from the raid in all which is nothing. I also got the samba process eating all 100 % of my cpu. I tried to move the files outside the raid but that didnt have any effect on the performance. Does anyone have an idea how i can speed up the performance? Is it possible that the locking slows down the performance so much? It was a windows fileserver before running win2k which was much faster on the same files. My other coworkers are almost lynching me cause i was the one who wanted linux cause of performance and security issues. Im happy about any suggestions.
