Try turning on verbose gc.
In particular, if you mark the start of a particular timing run by printing a line to output and then collect the GC output between those marks, you can determine total garbage collected. A bit of averaging later and you have the number you seek. Mis-sizing the newspace could be done to get more frequent collections and thus more resolution, but I doubt you need that. There are more elaborate methods using JMX, but this should do. http://java.sun.com/docs/hotspot/gc1.4.2/example.html On 3/10/08 6:02 PM, "Jason Rennie" <[EMAIL PROTECTED]> wrote: >> Were you able to measure garbage production? >> > > How would I do that? > > Jason
