This may be the client rescanning the directory after a delete. If the application is braindamaged enough to create 150k files in a directory it's stupid enough to rescan also. > I tried the suggestions on this page: > http://mirrors.uol.com.br/pub/samba/HOWTO/Samba-LargeDirectory-HOWTO > > But that didn't make any difference either. > > I also put together a Linux test box (1.5GHz P4, Ubuntu Dapper Beta 7, Samba > 3.0.22, ext3 file system) and the performance issue is not present on that > platform. Hmmm. So the problem doesn't occur on a Linux+ext3 box, but does on an AIX+jfs box - with the same version of Samba.... I can see a pointer to the problem here, and it doesn't look like Samba to me :-).
