VMware Explore happening NOW!

Some Numbers

As I get into this performance thing with Mr Kevin. I thought I’d share a few numbers from early builds and what not. You know, the sort of “should we do this” thing kind of stuff.

These nubmers are for a 5 node build using the Vagrantfiles here:

Node CPU Ram
Controller 1 1 1.5GB
Controller 2 1 2GB
Compute 1 2 2GB
Cinder 1 1 .5GB
Chef 1 1GB

The hardware involved is a late 2013 Retina MacBook Pro:
– 2.5 Ghz Core i5
– 8GB Ram
– SSD

Note, this environment will be similar, but not the only environment we build out for the OpenStack Summit and the Performance book. The theory being, a change or two here can be more quickly tested for positive or negative effect than rebuilding a full deployment.

Results

Below are the best results of 3 reach for each setup.

Some other things about this:
– I have no horse in the race for either platform or OS. Just running some vagrant-ups.
– This is done over 3 runs of each. Mostly not using the laptop. Basically, I did a /lot/ of reading during this time.
– These are pretty manila. That is, no caching, no performance hacks on Fusion or vBox.
– Virtualbox and my MacBook don’t get along under the load of the environment. Basically after hours of lost time, many hard crashes, and such, I’m going with “n/a” on performance numbers for vBox. At least for now.

Notes on Virtualbox:
During the testing for anything on virtualbox in this list, I encountered no small amount of hard crashes. For CentOS alone, about 15 hours was sunk. As I stated before, I don’t have a horse in the race between one or the other, but damn was this a challenge. If you can make it run and don’t mind helping, drop a comment with the output of time vagrant up --provider=virtualbox for this environment, and what hardware you’re running it on.
