Yup. Or Zones.  The hardware itself is dedicated to the testing, so it should have plenty of horsepower.

> Chris - another thing that is worth checking is whether any previous tests are leaving looping threads. These tests are running sequentially in the same VM and we have had cases in the past where a test creates a daemon thread that heads off into the weeds, leading to slow down in subsequent tests. I tracked down a few of these last year and don't think we have any now but worth re-checking.

Yup. Could be a major impact being run as a jtreg -agentvm batch.

Yup. Me too.
