Hi Venkat -- user: process virtual user time, sys: process-virtual system time real: elapsed time
Re: "Use showing more than 3 mins" : depends on how many cpus you have. Really, what should typically concern you, as a user of GC, is the "real" time above, which is the duration for which your threads are stopped (when the time is associated with a stop-world pause). For concurrent ops, it's the end to end elapsed time for that cycle, so should not typically be of concern, as your application threads are running during that time. cheers. -- ramki On Sat, Apr 13, 2013 at 1:37 PM, Venkateswarlu Mandadi <mndv...@gmail.com> wrote: > Hi, > > We are using CMS collector for oldgen (large heap -Xmx18g) and we have > observed there is a long whole world stop, in GC logs it was observed that > GC times are looking alright, but Times: Usr showing around more than 3 > mins. > > Can someone explain Times fields > > Times: user=0.45 sys=0.00, real=0.09 secs > > Best Regards, > > Venkat
