450,000 LDAP Operations per Second

Benoit Chaffanjon did an interesting "Benchmarketing" (you have to read his blog to understand why he calls it that) that showed Directory Server Enterprise Edition may be able to support 450,000 + LDAP operations per second.   The benchmarketing was done on a Sun Blade 6000 using the Intel Xeon x5560 on OpenSolaris.  All the gory details can be read in Benoit's blog here.  This is mind-blowing when you consider the cost of transaction per second and also what this might look like on an SSD.  We are doing some further testing as Mark Craig mentions in his blog not only to validate these amazing results but also to confirm the performance using OpenSSO and on a SSD.
