Git deploy for chef
I’ve been doing a lot of work with chef lately and the default workflow really sucks. Typically what I will do is make a change, commit it, then push it up to github. Then I will login to my chef server and run rake install in /var/chef-repo to pull from github and upload all the new cookbooks and roles into the running chef instance. Then I will login to the target server and run...

Performance Followup from NoSQL
I was at the NoSQL meetup in SF two weeks ago to present about Dynomite and I had a great time. There has been some discussion afterwards about the various performance numbers bandied about and I wanted to speak for Dynomite about the exact meaning of the performance numbers I present in my slides. And generally, I wanted to talk about what I think is a superior approach to performance testing...

Ludicrous Speed
One of my goals with Dynomite is to make it a high throughput system. It should be able to scale horizontally as hardware is added. But it should also be able to scale vertically and fully utilize hardware with varying degrees of capability. I wanted to get a baseline throughput reading for what could be called a single large instance.
So I setup a test to see what a single node could handle...

Deferring gen_server responses
I’ve been doing a lot of throughput optimizations on Dynomite lately. I got the unsaturated latency down to a point where I was happy with it, so the next step was to optimize the throughput of a fully saturated node. Generally when I find something interesting or at least strike something off the list as being a culprit for throughput issues I’ll fire off a cryptic message into the...

AppEngine
AppEngine is not google competing with AWS. It is an incubator for acquisition targets. Computer time is cheap, but developer time is not. So why not get a bunch of unpaid developers to write apps that are tailored to your platform. Then you can buy the good ones at a bargain basement price. The cost of migrating off the google platform will devalue the company to any other suitors.

Shipping around lots of small files
Shipping around small files sucks. SCP takes forever and a day. Tossing them into a tarball and sending them over would take just as much time in total. Courtesy of Brian McCallister:
On the destination machine:
nc -vl 9000 | cpio -id
And on the source machine:
find ./my/data/lives/here | cpio -o | nc -v destination.blah.com 9000
Significantly faster. I clocked scp at 628k/sec and...
