Any idea what is the unit of "+user I/O wait time+" in the
V$MYSTAT performance view? This stat is not listed in Appendix E of the
Oracle® Database Reference guide.
The unit used in other v$ views (e.g. <i>V$SQLSTATS</i>) says microseconds.
Want to be sure it is too in
V$MYSTAT.. as if so, then I'm seeing an unexpectedly low latency in the I/O subsystem via this stat.. :-)
