slamd results have been interesting. The same set of clients that easily push 
back-hdb up to 62,000 searches/second at 1485% CPU use are gasping and dying, 
pushing back-mdb over 75,000 searches/second at only 1000% CPU use. Once again 
I need to bring some more load generator machines online in order to actually 
max out slapd.
