Dear all When database files are on a VxFS filesystem, performance can be significantly improved by setting the VX_CONCURRENT cache advisory on the file according to vxfs document,
my question is that have any tested by this? #include <sys/fs/vx_ioctl.h> ioctl(fd, VX_SETCACHE, VX_CONCURRENT); Regards HSIEN WEN -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
