Re: [Gluster-devel] [Gluster-users] Status of the SAMBA module

[RAGHAVENDRA TALUR]

Hi,

1. Please add in global section in smb.conf the following lines:

kernel oplocks = no

stat cache      = no

2. service smb restart

Please try the same test and let us know if that helps to increase the throughput.
