Hi Geoff, Thanks for reply. I understood meaning of the fields in varnish 6.
One answer I got that we should consider 0.048125 as total response time. But my actual question is different. I am not getting difference between varnish 3 and varnish 6. Exact question if I ask.. *varnish 3* ReqEnd c 877345549 1233949945.075706005 1233949945.075754881 0.017112017 0.000022888 *0.000025988* *varnish 6.1* Timestamp Resp: 1501601912.806787* 0.048125* *0.000037* *0.000025988 (varnish 3) is equivalent to 0.048125 or 0.000037 (varnish 6) ?* we have upgraded from 3 to 6 so not able to decide exact field which I was reading in case of varnish 3. *Thank you* *Hardik* On Mon, 18 Mar 2019 at 16:52, Geoff Simmons <[email protected]> wrote: > On 3/18/19 12:09, Hardik wrote: > > > > *varnish 6.1* > > Timestamp Resp: 1501601912.806787 0.048125 *0.000037* > > > > > https://feryn.eu/blog/varnishlog-measure-varnish-cache-performance/#The_Timestamp_tag > > > > > > -> Are both fields give same values, means same meaning or both are > > different?
