 ## Environment
 
-Bare metal Rackspace instance Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz 20 physical cores 40 hyperthreaded CPU
+[Bare metal Type 2 Packet instance 24 Physical Cores @ 2.2 GHz (2 × E5-2650 v4)](https://www.packet.net/bare-metal/)
 
-   * https://www.rackspace.com/en-us/cloud/servers/onmetal/specs see Compute specs
+   * The [Techempower benchmarks](https://www.techempower.com/benchmarks/#section=environment&hw=ph&test=fortune) use a [2.0 GHz processor](http://ark.intel.com/products/53574/Intel-Xeon-Processor-E7-4850-24M-Cache-2_00-GHz-6_40-GTs-Intel-QPI) on the Dell R910
 
 Need to add at least one server to the proxy prior to testing:
 
 ```
 $ curl -vvv -H "Host: www.example.com" localhost:8687/servers -d '{"url":"http://127.0.0.1:12345"}'
 ```
 
+Note: For a real test, should be running on its own server.
+
 ## Tests
 
    * techempower plaintext benchmark per https://www.techempower.com/benchmarks/#section=code
 
 ### wrk
 
+To run the plaintext benchmark using `wrk`:
+
    * example command: `wrk --connection 100 --duration 30s --threads 4 http://localhost:8080`
    * techempower plaintext benchmark: `wrk -c 256 -t 32 -d 15 -s ./benchmark/pipeline.lua --latency http://localhost:8080 -- 16`
 
+Note: For a real test, `wrk` should be running on its own server.
