Re: Max number of entries

[Matthew Backes <lucca@csun.edu>]

Performance ceilings are in general more dependent upon database 
configuration with respect to cache size, checkpoint interval, etc.

For a really good guide to tuning, take a look at the Sleepycat 
documentation for Berkeley databases.  Most of back-bdb's database 
configuration is done using bdb's DB_CONFIG file.

With a properly tuned database and enough ram, the world is yours for 
the taking.

If you have very strange needs, such as tens of thousands of attributes 
on a single object, or tens of thousands of values per attribute on a 
single object, you may wish to do testing.  It's been my experience 
that most commercial products tend to do far worse for strange cases 
though.
