30 May 06 - 13:09An Answer to "What is the best way of storing identity data?"

Johannes Ernst raises the question, "what is the best way of storing identity data?". And he's struggling to create a requirement for something other than a Directory. He wasn't very convincing ... just my humble opinion. (more)

22 May 06 - 08:31Benchmarks: Round One

We got intrigued by the benchmarks published by Neil Wilson comparing a Dell server to Sun's new T2000 servers. Then Sun offered loaner T2000 units to application developers. We jumped at the chance.

Connexitor™ Directory Services (CDS) (Symas's certified, tested, and natively installable binary distribution of OpenLDAP performed 19% to 31% more user authentications a second (faster) than Sun Java™ System Directory Server (JSDS) on the T2000. We ran the same workload on an HP Integrity dual Itanium 2 server and saw 27% to almost 32% further increase in authentications per second. A SunFire 4100 dual Opteron system showed another 26% to almost 30% performance improvement on the same workload. The Sunfire 4100 running CDS was just over twice as fast as SJSD on the T2000 (and sneaking up on three times as fast as SJDS on the Dell unit).

What we learned in school today? These Sun and HP servers can casually handle authentication workloads in excess of one million user entries (with RAM, in excess of 5 million or more because OpenLDAP's performance has been proven to be relatively flat into the tens of millions given enough RAM) and at authentication rates indicative of the loads seen in large campus environments. What was a big scary directory a couple of years ago can now be run well on solid commercial offerings.

Read on for the rest of the story.

Perfect timing. Symas wants to keep one.

08 May 06 - 07:20A RedHat/SuSE without the distro?

I spent a while on the OpenLogic site after reading this clueless breathless article to see what Open Source projects they support. The proposition looks like they're making a play to be the Level 1 and Level 2 technical support aggregators ... but they've got a number of their own technologies. Wonder if that's Open Source too! Never did figure out what technologies they do support ... maybe I'm just impatient. (more)
