This screenshot was taken on my dev box which has plenty of other activity happening. On a production memcache box, seeing 1Gb/s, I see ~2% packet loss.

Since I wrote memkeys, maybe I can clarify a few things. First, dropping packets matters. If you see only 30-40% of your traffic you can't guarantee that you have enough data to know what your hot keys actually are. This is especially true

I'm just going to point out that this site is hosted by wisegeek.com, a site that was hit hard by the panda update (see http://www.quantcast.com/wisegeek.com ). Although the data is accurate, I wouldn't feel sorry for most of these sites.

Hey Steve, we do have plans to open source the code in two parts. The first part to likely be open sourced will be the high performance logging library that was written for it. After that, the proxy component. Keep an eye on the Tumblr engi

The upper band essentially represents new users. At the current rate of growth, we push into a new redis shard every 2-3 days. When we first start writing/reading against that shard, it appears to take a bit of time to warm up.

I worked on Staircar so maybe I can answer a couple of questions. Machine failures: failures we'll likely address in a future post but basically each redis instance can have a slave which can be failed over to. Performance: Staircar isn't n

Great documentation, like the previous commenter mentioned. Question, is this just a drupal installation or what?

Remember the underpants gnomes from South Park? Their plot was simple. 1. Steal underpants, 2. ???, 3. Profit. Most YC people have something similar going on: 1. Come up with great idea, 2. Get YC to fund it, 3. ???, 4. Profit, 5. Get a Gir

If you can afford it, UltraDns (Neustar) is the best. This is the service that Amazon uses, as well as a number of other very large sites. They have a 100% uptime SLA and a latency one as well. We haven't had an outage with them in almost t

Oracle is just 'allowing' you to use the product on EC2. You don't get utility licensing. See http://blog.mobocracy.net/2008/09/oracle-does-not-enter-aws-...

We use The Planet ( http://www.theplanet.com ) along with EC2 from AWS. I've used The Planet for about 7 years now, for both business and personal use. Good prices, decent support and a top notch network.

Having used RoR and Spring fairly extensively, I was convinced that Groovy, and more specifically Grails, would be great to work with. Fun? Check. New? Check. Bleeding edge unstable? Check. Extremely difficult to figure out how to do things

Just note that you are limited to 5k queries per 24 hours per IP address with this. Like Tony said, NOT for production.

I've used JMeter ( http://jakarta.apache.org/jmeter/ ) for a few years now. It's easy to use and extend. The only thing I don't like is it doesn't play nice with AJAX.

Keynote DOES measure the time it takes for a page to be rendered using IE, Firefox, Safari and Opera.

I'm thinking this might be a 'bad' idea unless you are also hosting the site on EC2. Having significant latency in your session handling will bring your site to a crawl due to IOWAIT on your web servers. Obviously making a request across th

There's a lot of overhead in running a MySQL instance compared with running a memcached instance (in terms of system resources, personnel, building it redundantly). I would revisit your problem and see if you can't get memcached to fit befo

I think Amazon should be part of your hosting strategy, but not the entirety of it. We use Amazon (EC2, S3, SQS) but only where appropriate. EC2 for compute intensive but ephemeral data (logging, etc since your storage can disappear). S3 fo
