It is waiting for the working set size (WSS) to freeze, which may take
a long time, depending on your request rate. Please see workload
descriptions on the web site or search for "working set" for details.

Also, your request rate is zero after the first 30 seconds of the
test. This most likely indicates a very low peak request rate; warm-up
phase uses 10% of the peak request rate and bursts of requests for
embedded objects may create long periods of inactivity. You may
"never" fill your working set at this rate.

You are not using any 2.8 features if you are using standard PolyMix
workloads, so most documents should apply as is or with just cosmetic
changes.

I am not sure what is going there without a complete console log from
both client and server side. If I have to guess, I would say that the
proxy somehow prevents the Polygraph server from communicating phase
information to Polygraph clients (e.g., the proxy may strip some HTTP
headers). This is a wild guess, however. I would need to see both
console logs to make more educated guesses.

The first phases of both workloads do not log any stats,
unfortunately. It was a useful feature at the time, but now
Polygraph's reporter can isolate stats based on phases and does not
need that old "feature".
