Hi, It seems low performance PostgreSQL(9.3.6) while writing data to glusterFS distributed file system. libgfapi is provide since GlusterFS version 3.4 to avoid kernel visits/data copy which can improve its performance. But I didn't find out any instruction from the PostgreSQL web page. Do you know if PostgreSQL later release supports using libgfapi to optimized write data to ClusterFS file system. -- View this message in context: http://postgresql.nabble.com/Does-PostgreSQL-support-to-write-glusterfs-by-Libgfapi-tp5877793.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
