[ovirt-users] job queue

Hello,  I have a question regarding the internal operations of ovirt- engine. It seems the internal queue only processes up to 10 requests / jobs simultanious. E.g. 7 Power_ON and 3 LiveMigrations. All remaining jobs (e.g. 50 more Power_On requests) are delayed. Is this queue size configurable somehow? We sometimes do have a huge amount of power_on requests (last time up to 700 in 30 minutes) that get extremely delayed by this. Any hints are welcome. best,  Dominique
