Hi, onstat -g sch gives two informations: VP Scheduler Stats and Thread MigrationStatistics. I'm looking for any information about Thread Migration Statistics. Does anyone know what is it about? What does it mean: 'steal-at steal-sc idlvp-at idlvp-sc inl-polls Q-ln'? I couldn't find anything in any docs I've got.

Those stats have to do with threads migrating from one CPU VP to another. Normally it is not frequent. Art S.
