[Samba] How to avoid CIFS timeout?

[Xiaoli Feng]

Hello Zhiye,

 On my opinion, you can improve the CIFS performance instead of avoiding CIFS 
timeout. Such as extend read/write size and change the cache type. I don't think
enable "async smb echo handler" is a good choice for your situation. This option
will depress performance.
