Thanks for your suggestion. I modified my smb.conf accroding
to those pdf docs, but the samba speed is still poor.
I try to build a proftpd server from source code and transfer these
small files through ftp and the speed hit 2.5Mbyte/s. But when
I copy large files through smbfs,the speed is normal.So I wonder
if it's all rely on the configuration of samba.Is there any
specific principles on performance tuning about small files transfers?
Any suggestion would be appreciated.
