New Features in Solaris Express 9/05

This section describes all features that are new or have been enhanced in the Solaris Express 9/05 release.

Dynamic Interrupt Distribution

This system performance enhancement is new in the Solaris Express 9/05 release.

The intrd daemon monitors loads on the system that are due to interrupts. If an imbalance is detected, the daemon retargets interrupts to new CPUs in order to balance the interrupt load. This feature should improve system performance under high interrupt loads.

The daemon is started by the new SMF service, svc:/system/intrd.

For more information, see the intrd(1M) man page.
