Performance and scalability: Full GC pause times with 1.3

  1. Full GC pause times with 1.3 (1 messages)

    Hi,
      I'm interested to see what pause times people are seeing, if anyone else is using Sun's 1.3.1 VM on Solaris (ie. Websphere 4.x on solaris). For heaps of 1 GB or larger. I'm seeing up to 1 minute pauses during full collection, which seems a bit a high to me though the overall throughput is not bad.

    Thanks!

    With JVM of 512 mbytes., I've seen typical full GC of about 4-5 seconds. If you are seeing pauses of 1 minute, then probably there is a configuration problem. Verify the configuration of eden, generations, and so on, because 60 seconds is a lot of time.
