Here is the description of the stress test for the re-engineered BDII.
 
The following test was conducted on a dual 1GHz Intel Pentium III machine
with 512Mb of Ram. The tests involved inserting information from an information provider script and pushing the data into the LDAP database whilst simultaneously being queried by 10 searches in parallel. The information provider script was the same the top level script as use in the performance testes, 1.8Mb of data from LCG1. The information provider script was run every 30 seconds and the data pushed into the database. The query process would fork off 10 queries and wait for them to return and then rest for 1 second before querying again.

The test ran for over two weeks, in which time over 2 million queries on the database had be done with no corruption of the LDAP database.
