server startup overhead

[Eric Irrgang <erici@motown.cc.utexas.edu>]

I continue to have trouble with getting a freshly started server to be 
responsive.  One problem in particular is one that I thought had been 
resolved some time ago but is apparently biting me right now...

With the hdb backend (at least in OL 2.3.34 and OL 2.3.35) if you perform 
a search with a search base deeper than the root suffix, the search takes 
a very long time to complete if the cache hasn't been established.  In my 
case the difference is less than a second versus several hours.  I'm not 
sure yet which bit of cache needs to be primed.  I can switch back and 
forth searching with the same filter in the root and then a child search 
base with the same results.

Is this a bug recursion or something that I just hadn't been noticing?

What would be the best search to perform to prepare whatever cache is 
getting hit to make searches outside of the root DN faster?
