can't comment on Linux, but a few points about Solaris: - does what you see persist over time (minutes)? - prstat may show a different picture - prstat -m shows per-process microstate accounting, this may enlighten you about what's triggering the load (if it persists) - have a go at DTrace, something like # dtrace -n 'profile-10...@[stack()] = count()}' interrupted after a few seconds will show you what the kernel's doing most of the time HTH -- regards/mit freundlichen Grüssen Michael Schuster _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
