Hi, I have detected a very low performance with cp command or any write with CIFS mount (Netapp Storage), <15mb/s. Read performance is similar Local disk perofrmance is correct >100mb/s fstab entry is : //netapp/resource$/folder /mnt/test cifs username=u,password=p,domain=dom,iocharset=utf8,uid=1001,gid=1000,dir_mode=0700,file_mode=0700,auto Server is SLES 12 SP3 with latest updates and samba samba-client-32bit-4.6.13+git.72.2a684235f41-3.21.3.x86_64 cifs-utils-6.5-9.3.2.x86_64 Any suggestion? Thanks

Have you tried using smbclient to test read/write performance to the NetApp ? If that is also slow then you have 2 different clients with the same problem. Time to look closely at the server...
Hi, How can I test with smbclient? any example?
