Disk I/O performance in a Guest LDOM is less than to a physical I/O device (Doc ID 1507158.1)

Last updated on AUGUST 31, 2023

Applies to:

Solaris Operating System - Version 11.1 to 11.1 [Release 11.0]
Solaris Operating System - Version 10 to 11 u1 10/12 [Release 10.0 to 11.0]
Oracle Solaris on SPARC (64-bit)


When you perform storage I/O tests (e.g. with dd(1), vdbench or other tools) and measure the I/O data throughput (e.g. with iostat(1))

then you might notice that the I/O performance is higher in the second situation.
