Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.

Bonus Track

ASP.Net 4.5.1 MVC 5 on IIS 8

I've benchmarked ASP.Net, since I do .Net at my day to day job. Rackspace doesn't offer an OnMetal instance with windows, only virtualized instances, so I've done the benchmarks on the most powerful one I could find.

On a Rackspace I/O v1 120GB instance is listed as:

CPU:	32 vCPUs
RAM:	120 GB
System Disk:	40 GB
Data Disk:	1.2 TB (4 disks)
Network:	10 Gb / s
Disk I/O:	Best

Results:

root@client:~# wrk -t20 -c100 -d30S --timeout 2000 "http://10.223.241.211/showdown"
Running 30s test @ http://10.223.241.211/showdown
  20 threads and 100 connections
  Thread Stats   Avg      Stdev     Max   +/- Stdev
    Latency    62.98ms  104.13ms 962.77ms   81.84%
    Req/Sec     1.02k   435.75     2.92k    70.76%
  581748 requests in 30.02s, 1.39GB read
Requests/sec:  19381.05
Transfer/sec:     47.37MB

Results were pretty horrid, but maybe it's the virtualization overhead, or maybe Rackspace's Windows virtualization is bad, or even the 10gbit network between OnMetal instances and virtualized instances is not that good. I might do more testing this weekend to try to figure that out.
