I am setting up a file server with CentOS 7. I'm seeing
performance which is considerably slower than a similar
server running CentOS 6.6. A 3Gb directory can be copied
to/from the CentOS 6.6 server in about 50 seconds. The
same directory takes about 270 seconds to copy to/from
the CentOS 7 system.
I see the same performance difference with NFS mounted
file systems or using scp, so it doesn't appear to be
an NFS issue. The MTU on the NICs on both systems is
1500, and changing it to 6000 on the CentOS 7 system had
no effect.
Anyone have any ideas what might cause this problem or
how to fix it?
