Yes, recent standard workloads such as PolyMix-2,3 can be used in your

Make sure that all polyclt and polysrv processes are using the same
PGL configuration. Also check that Robots' public_interest is
positive. It is positive in standard workloads. This will ensure that
Robots from different machines will share the specified portion of the
URL space, making peer hits possible.
You may also need to play with the working set size and popularity
model to get the desired effect (i.e., more/less peer hits and
I only used load balancing approach to aggregate proxies, so I may be
missing some important points. Depending on your testing goals, you
may have to adjust standard workloads.
