---------------------------------------
[~stakiar] thanks for working on it. I would like to lend my hand in this
effort.

> I've been taking a look at the Disk, Network, and CPU usage of the GCE
> instances we run ptest on, and it doesn't look like we are fully utilizing
> the machines. The resource usage is very up and down.
> During each ptest execution, there is a large chunk of time (~20 min) where
> its just the Jenkins job that is doing any work (checking out github repos,
> building code, figuring out test batches, etc.). During this time, the ptest
> nodes are mostly idle - the CPU and Disk I/O are almost zero.
> Even when ptest is running, I think some of resources are under-utilized.
> Network and disk resource spike at the beginning of the job, probably because
> ptest is distributing resources to each machine, each slave is downloading
> jars, etc. However, after that, when the actual tests run, there is almost 0
> network activity (which makes sense since tests runs on a single node). For
> disk usage, there is activity, but not nearly as high as when the setup phase
> was occuring. CPU usage fluctuates between 40-80%.
