  We'd tried improving the performance of GDBM some, but at this point, I
  can't honestly recall which version we tried or which things we tried to
  tune.
  
  Our problematic case though is a particularly nasty one. It isn't our
  usual runtime problem but rather the compilation of a DB from the text
  form into the binarydb. With a large DB (about 1.5G) consisting of
  roughly 1.1 million objects, DB compilation was taking between 6 and 13
  hours. Through profiling, we determined that this was due to the speed
  of record insertion into our DBM-based index. In fact, if we deferred
  all DBM insertions until after the actual compilation had happened by
  keeping a big hash of the records in memory, we could get through the
  actual compilation process in roughly 30-40 minutes, followed by several
  hours of waiting while the DBM index was populated.
  
  I wrote a small benchmarking program that just created a given number of
  keys and started to look at tuning the performance of DBM, BDB's DBM
  emulation layer and using BDB directly. I had no luck with the DBM or
  BDB-DBM approaches, but using BDB directly and setting a very large
  cache size (about 145M), I could insert 2.2M records in about 2 minutes.
  Dropping that cache size had the effect of increasing the amount of
  time non-linearly. Our working assumption became that we could (and
  should) just work with different cache sizes for compilation and normal
  runtime usage, which has been working fairly well on a test server of
  mine. That server runs Solaris, so the comparisons against DBM for
  runtime operations has been against the Solaris DBM rather than either
  the FreeBSD NDBM or GDBM. (My original benchmarking was on FreeBSD
  though since that's what the main server that I care about runs at the
  moment.)
  
  I would love to hear that I'm wrong or that I missed something and that
  I can get equivalent levels of performance out of GDBM. :) It'd make
  life much easier on me to not have to introduce a dependency on BDB
  3.2.9 for Cold, or alternatively, to have to maintain 2 versions of our
  lookup index code.

  Cold does store 2 records per object. But the first, symbol->objnum is
  cached within the driver which avoids most of the common hits to that
  DB. Currently, objnum->seekaddr isn't cached (I'm not sure why, this is
  old code), but I've recently introduced some code to avoid re-writing
  that value if it isn't necessary to do so. (That change has no impact o
  the DB compilation phase which has been our main worry.) Currently, our
  disk I/O patterns only involve the objnum->seekaddr index and the block
  file. With BDB and an appropriate cache size, we should be avoiding
  most of the index updating.
  
  There were some stupid things happening in that code within Cold as
  well, like serializing integral values to strings and so on, and using a
  single DBM file to store both indices, with associated hackery to
  determine which index a particular key/value pair belonged to. I
  removed all of that, found a way to remove some strlen() calls which
  shaved about 30-45 seconds off of the 40 minute compile time and made
  the code much easier to understand conceptually.

  See above. It was strictly testing the speed of DBM operations when
  there are many many records.
  
  Since Cold requires a decompile/recompile of the binary database when
  doing upgrades of the driver, this was very important work as it dropped
  the required maintenance window for upgrading a large game from
  somewhere over 15 hours to under 3, possibly under 2. (For a typical
  small game, you'd be seeing decompile/recompile times that are well
  under 10 minutes, both with the old and new lookup index code.) This
  work also resulted in us returning to being CPU bound during DB compilation.
