Irrespective of whether a given GC algorithm is blocking or not, I would be concerned about elapsed time since it's CPU spent on GC, not on application tasks. Whether the JVM logs GC elapsed times isn't a particularly useful metric as to whether pauses are happening or not. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
