[Gluster-users] gfs vs nfs: abysmal performance difference
Dear, we are evaluating Glusterfs as an alternative to NFS. I connected two boxes (a dell 2950 and a via epia) with a crossover cable: the via epia is the gfs server, the 2950 is the client, and both run freebsd 7.2. i exported /usr/src via gfs and nfs, and then i ran a buildkernel session: gfs: >>> Kernel build for GENERIC started on Mon May 11 10:14:31 CEST 2009 Kernel build directory is /usr/obj/mnt/gfs/sys/GENERIC >>> Kernel build for GENERIC completed on Mon May 11 11:07:18 CEST 2009 ~53mins nfs: >>> Kernel build for GENERIC started on Mon May 11 11:07:51 CEST 2009 Kernel build directory is /usr/obj/mnt/nfs/usr/src/sys/GENERIC >>> Kernel build for GENERIC completed on Mon May 11 11:23:13 CEST 2009 ~16mins are these numbers expected? anything i can do to tune gfs? -- Paolo Pisati Reparto Sistemi --------- ContactLab Via Natale Battaglia, 10 20127 Milano (Italy) Tel. +39 02 28 31 181 Fax +39 02 70 03 02 69. http://www.contactlab.com
