I think you've got plenty of good ideas for possible optimizations. But first, have you profiled your app? If not, break out something like Devel::DProf or Devel::Profile. These can tell you if your DB access is really your bottleneck. If it is, try making these changes and validate them by re-running the profiler, or by using Benchmark (but be sure to re-profile before declaring success!).

And just because I can't help myself, you might consider the fact that you're probably double-hashing your data. You hash something to produce an MD5 key and then SDBM re-hashes that key into an internal key. That's probably a waste of time - perhaps you could feed SDBM a natural key instead, if you have one.
