How similar in performance is MDBM to GDBM (the GNU DBM)? They appear to be similar (if not identical) in functionality.

- api 12y agoNot sure, but in my experience GDBM is a bit on the slow side. MDBM uses mmap(), so for that reason alone it should be faster.
- luckydude 12y agoMDBM was designed to be fast with special care taken on the lookup path. The goal was to do lookups with as few cache misses as possible. You can get to any key with at most two page faults.
- cbsmith 12y agoThey might appear similar, but that's just because they share the same DBM interface heritage.
