The speed of copy is very very slow when much files in the folder

[Zhangxiaoxu]

Hi,

100,000 files in my share.
When I copy some little files to the folder, the speed is very very slow.

I add some logs in the smbd, the “get_real_filename_full_scan” function cast about 1s. It’s too slow.
I think the function is used for comparing the dest name to the exist files to check whether the dest file is exist.

When I add “case sensitive = yes” to the configuration file, the speed is much quickly.

So, I think whether we has some method to improve the performance?
Could you give us some suggestion about the case.

Environment:
       Ubuntu 14.04
       Samba 4.3.11

Client:
       Windows 7

Configuration:
       clustering = yes
       ctdbd socket = /var/run/ctdb/ctdbd.socket
   max protocol = SMB3
   large readwrite = yes
   idmap config *:range = 1000000-1999999
   log level = 2
   use sendfile = yes
   store dos attributes = yes
   acl_xattr:ignore system acls = yes
   aio read size = 1024
   deadtime = 10
   aio write behind = true

Could you add my bugzilla account to the samba domain.
