 14.4.5 Things We Need to Fix for `BDB'
 --------------------------------------
 
    * It's very slow to open many `BDB' tables at the same time. If you
      are going to use `BDB' tables, you should not have a very large
      table cache (for example, with a size larger than 256) and you
      should use the `--no-auto-rehash' option when you use the `mysql'
      client.  We plan to partly fix this in 4.0.
 
    * `SHOW TABLE STATUS' doesn't yet provide very much information for
      `BDB' tables.
 
    * Optimize performance.
 
    * Change to not use page locks at all for table scanning operations.
