I don't want to flush the buffer cache but need to verify disk IO speeds on 3
servers in my rac cluster. According to DBA_HIST_SQLSTAT, the elapsed times
for some queries are significantly slower on one of the 3 nodes.
I've done a cursory glance at slob and it seems a bit complicated for what I
want to do here *if* there is an option to force physical reads and bypass the
buffer cache.
